            NOW, THEREFORE, BE IT RESOLVED, that for good and adequate
consideration, the receipt of which is hereby acknowledged, the parties hereto

                                 DEFINED TERMS

Section 1.1 Definitions.

            The following definitions shall be for all purposes, unless
otherwise clearly indicated to the contrary, applied to the terms used in this
Agreement.

            "Act" means the Maryland Revised Uniform Limited Partnership Act, as
it may be amended from time to time, and any successor to such statute.

            "Additional Funds" shall have the meaning set forth in Section
4.3.A.

            "Additional Limited Partner" means a Person admitted to the
Partnership as a Limited Partner pursuant to Section 12.2 and who is shown as
such on the books and records of the Partnership.

            "Adjusted Capital Account Deficit" means, with respect to any
Partner, the deficit balance, if any, in such Partner's Capital Account as of
the end of the relevant fiscal year, after giving effect to the following
adjustments:

            (i)   such deficit shall be decreased by any amounts which such
                  Partner is obligated to restore pursuant to this Agreement or
                  is deemed to be obligated to restore pursuant to Regulations
                  Section 1.704-1(b)(2)(ii)(c) or the penultimate sentence of
                  each of Regulations Sections 1.704-2(i)(5) and 1.704-2(g)(1);

                  Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6).

            The foregoing definition of Adjusted Capital Account Deficit is
intended to comply with the provisions of Regulations Section
1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. A positive

described above in clauses (i) and (ii), is referred to in this Agreement as an
"Adjusted Capital Account Balance."

            "Adjustment Date" means, with respect to any Capital Contribution,
the close of business on the Business Day last preceding the date of the Capital
Contribution, provided, that if such Capital Contribution is being made by the

into or exchangeable for REIT Shares), then the Adjustment Date shall be as of
the close of business on the Business Day last preceding the date of the
issuance of such securities.

            "Affiliate" means, with respect to any Person, any Person directly
or indirectly controlling, controlled by or under common control with such
Person. Control of any Person means the power to direct the management and

of voting securities, by contract or otherwise, and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.

            "Agreed Value" means (i) in the case of any Contributed Property set
forth in Exhibit A and as of the time of its contribution to the Partnership,
the Agreed Value of such property as set forth in Exhibit A; (ii) in the case of
any Contributed Property not set forth in Exhibit A and as of the time of its
contribution to the Partnership, the fair market value of such property or other
consideration as determined by the General Partner, reduced by any liabilities
either assumed by the Partnership upon such contribution or to which such
property is subject when contributed; and (iii) in the case of any property
distributed to a Partner by the Partnership, the fair market value of such
property as determined by the General Partner at the time such property is
distributed, reduced by any liabilities either assumed by such Partner upon such
distribution or to which such property is subject at the time of the
distribution as determined under Section 752 of the Code and the Regulations
thereunder.

            "Agreement" means this Amended and Restated Agreement of Limited
Partnership, as it may be amended, modified, supplemented or restated from time
to time.

            "Appraisal" means with respect to any assets, the opinion of an
independent third party experienced in the valuation of similar assets, selected
by the General Partner in good faith; such opinion may be in the form of an
opinion by such independent third party that the value for such property or
asset as set by the General Partner is fair, from a financial point of view, to
the Partnership.

            "Assignee" means a Person to whom one or more Partnership Units have
been transferred in a manner permitted under this Agreement, but who has not
become a Substituted Limited Partner, and who has the rights set forth in
Section 11.5.

            sale, exchange, disposition, or refinancing during such period
            (excluding any sale or other disposition of all or substantially all
            of the assets of the Partnership or a related series of transactions

            or substantially all of the assets of the Partnership), and

                  d. all other expenditures and payments not deducted in
            determining Net Income or Net Loss for such period,

            period,

                  f. the amount of any increase in reserves established during
            such period which the General Partner determines are necessary or

liquidation of the Partnership.

Agreement relating to the maintenance of Capital Accounts are intended to comply
with Regulations Sections 1.704-1(b) and 1.704-2, and shall be interpreted and

General Partner, or the Limited Partners) are computed in order to comply with
such Regulations, the General Partner may make such

public offering price per share of such class of capital stock sold.

and Section 4.3.C in connection with the contribution of Property or cash to the

provided, that if the contributing Partner is the General Partner, then, except
with respect to the General Partner's initial Capital Contribution which shall
be determined as set forth on Exhibit A, the determination of the fair market

adjusted to equal their respective gross fair market values, as determined by
the General Partner using such reasonable method of valuation as it may adopt,
provided, however, that for such purpose, the net value of all of the
Partnership assets, in the aggregate, shall be equal to the Deemed Value of the
Partnership Interests of all classes of Partnership Interests then outstanding,
regardless of the method of valuation adopted by the General Partner,

                  reasonably determines that such adjustment is necessary or
                  appropriate to reflect the relative economic interests of the
                  Partners in the Partnership;

            (iii) the liquidation of the Partnership within the meaning of
                  Regulations Section 1.704-1(b)(2)(ii)(g); and

(or decreased) to reflect any adjustments to the adjusted basis of such assets
pursuant to Code Section 734(b) or Code Section 743(b), but only to the extent
that such adjustments are taken into account in determining Capital Accounts
pursuant to Regulations Section 1.704-1(b)(2)(iv)(m); provided, however, that
Gross Asset Values shall not be adjusted pursuant to this subparagraph (d) to
the extent that the General Partner reasonably determines that an adjustment
pursuant to subparagraph (b) is necessary or appropriate in connection with a
transaction that would otherwise result in an adjustment pursuant to this
subparagraph (d).

            (e) If the Gross Asset Value of a Partnership asset has been
determined or adjusted pursuant to subparagraph (a), (b) or (d), such Gross
Asset Value shall thereafter be adjusted by the Depreciation taken into account

actually or Constructively Owns a 25% or greater capital interest or profits
interest in the Partnership, it does not and will not, without the prior written
consent of the General Partner, actually own or Constructively Own (a) with
respect to any Tenant that is a corporation, any stock of such Tenant, and (b)
with respect to any Tenant that is not a corporation, any interests in either
the assets or net profits of such Tenant.

            (2) Except as provided in Exhibit F, at any time such Partner
actually or Constructively Owns a 25% or greater capital interest or profits
interest in the Partnership, it does not, and agrees that it will not without
the prior written consent of the General Partner, actually own or Constructively
Own, any stock in the General Partner, other than any REIT Shares or other
shares of capital stock of the General Partner such Partner may acquire (a) as a
result of an exchange of Tendered Units pursuant to Section 8.6 or (b) upon the
exercise of options granted or delivery of REIT Shares pursuant to any Stock
Plan, in each case subject to the ownership limitations set forth in the General
Partner's Charter.

            (3) Upon request of the General Partner, it will disclose to the
General Partner the amount of REIT Shares or other shares of capital stock of
the General Partner that it actually owns or Constructively Owns.

            (4) It understands that if, for any reason, (a) the representations,
warranties or agreements set forth in E(1) or (2) above are violated, or (b) the
Partnership's actual or Constructive Ownership of REIT Shares or other shares of
capital stock of the General Partner violates the limitations set forth in the
Charter, then (x) some or all of the Redemption rights of the Partners may
become non-exercisable, and (y) some or all of the REIT Shares owned by the
Partners may be automatically transferred to a trust for the benefit of a
charitable beneficiary, as provided in the Charter.

            (5) Without the consent of the General Partner, which may be given
or withheld in its sole discretion, no Partner shall take any action that would
cause the Partnership at any time to have more than 100 partners (including as
partners those persons indirectly owning an interest in the Partnership through
a partnership, limited liability company, S corporation or grantor trust (such
entity, a "flow through entity"), but only if substantially all of the value of
such person's interest in the flow through entity is attributable to the flow
through entity's interest (direct or indirect) in the Partnership).

      F. The representations and warranties contained in Sections 3.4 shall
survive the execution and delivery of this Agreement by each Partner and the
dissolution and winding-up of the Partnership.

      G. Each Partner hereby acknowledges that no representations as to
potential profit, cash flows, funds from operations or yield, if any, in respect
of the Partnership or the General Partner have been made by any Partner or any
employee or representative or Affiliate of any Partner, and that projections and
any other information, including, without limitation, financial and descriptive
information and documentation, which may have been in any manner submitted to
such Partner shall not constitute any representation or warranty of any kind or
nature, express or implied.

Section 3.5 Certain ERISA Matters

            Each Partner acknowledges that the Partnership is intended to
qualify as a "real estate operating company" (as such term is defined in the
Plan Asset Regulation). The General Partner may structure the investments in,
relationships with and conduct with respect to Properties and any other assets
of the Partnership so that the Partnership will be a "real estate operating
company" (as such term is defined in the Plan Asset Regulation).

                                   ARTICLE 4.
                              CAPITAL CONTRIBUTIONS

Section 4.1 Capital Contributions of the Partners

            At the time of their respective execution of this Agreement, the
Partners shall make or shall have made Capital Contributions as set forth in
Exhibit A to this Agreement. The Partners shall own Partnership Units of the
class or series and in the amounts set forth in Exhibit A and shall have a
Percentage Interest in the Partnership as set forth in Exhibit A, which
Percentage Interest shall be adjusted in Exhibit A from time to time by the
General Partner to the extent necessary to reflect accurately exchanges,
redemptions, Capital Contributions, the issuance of additional Partnership Units
or similar events having an effect on a Partner's Percentage Interest. Except as
required by law, as otherwise provided in Sections 4.3, 4.4 and 10.5, or as
otherwise agreed to by a Partner and the Partnership, no Partner shall be
required or permitted to make any additional Capital Contributions or loans to
the Partnership. Unless otherwise specified by the General Partner at the time
of the creation of any class of Partnership Interests, the corresponding class
or series of capital stock for any Partnership Units issued shall be REIT
Shares.

Section 4.2 Loans by Third Parties

            Subject to Section 4.3, the Partnership may incur Debt, or enter
into other similar credit, guarantee, financing or refinancing arrangements for
any purpose (including, without limitation, in connection with any further
acquisition of Properties) with any Person that is not the General Partner upon
such terms as the General Partner determines appropriate; provided that, the
Partnership shall not incur any Debt that is recourse to the General Partner,
except to the extent otherwise agreed to by the General Partner in its sole
discretion.

Section 4.3 Additional Funding and Capital Contributions

      A. General. The General Partner may, at any time and from time to time
determine that the Partnership requires additional funds ("Additional Funds")
for the acquisition of additional Properties or for such other Partnership
purposes as the General Partner may determine. Additional Funds may be raised by
the Partnership, at the election of the General Partner, in any manner provided
in, and in accordance with, the terms of this Section 4.3. No Person shall have
any preemptive, preferential or similar right or rights to subscribe for or
acquire any Partnership Interest, except as set forth in this Section 4.3.

      B. Issuance of Additional Partnership Interests. The General Partner, in
its sole and absolute discretion, may raise all or any portion of the Additional
Funds by accepting additional

                                       20
<PAGE>

Capital Contributions of cash. The General Partner may also accept additional
Capital Contributions of real property or any other non-cash assets. In
connection with any such additional Capital Contributions (of cash or property),
the General Partner is hereby authorized to cause the Partnership from time to
time to issue to Partners (including the General Partner) or other Persons
(including, without limitation, in connection with the contribution of property
to the Partnership) additional Partnership Units or other Partnership Interests
in one or more classes, or one or more series of any of such classes, with such
designations, preferences and relative, participating, optional or other special
rights, powers, and duties, including rights, powers, and duties senior to then
existing Limited Partner Interests, all as shall be determined by the General
Partner in its sole and absolute discretion subject to Maryland law, and as set
forth by amendment to this Agreement, including without limitation, (i) the
allocations of items of Partnership income, gain, loss, deduction, and credit to
such class or series of Partnership Interests; (ii) the right of each such class
or series of Partnership Interests to share in Partnership distributions; (iii)
the rights of each such class or series of Partnership Interests upon
dissolution and liquidation of the Partnership; and (iv) the right to vote,
including, without limitation, the Limited Partner approval rights set forth in
Section 11.2.A; provided, that no such additional Partnership Units or other
Partnership Interests shall be issued to the General Partner unless either (a)
(1) the additional Partnership Interests are issued in connection with the
grant, award, or issuance of shares of the General Partner pursuant to Section
4.3.C below, which shares have designations, preferences, and other rights
(except voting rights) such that the economic interests attributable to such
shares are substantially similar to the designations, preferences and other
rights of the additional Partnership Interests issued to the General Partner in
accordance with this Section 4.3.B, and (2) the General Partner shall make a
Capital Contribution to the Partnership in an amount equal to the net proceeds
raised in connection with such issuance, or (b) the additional Partnership
Interests are issued to all Partners holding Partnership Interests in the same
class in proportion to their respective Percentage Interests in such class. The
General Partner's determination that consideration is adequate shall be
conclusive insofar as the adequacy of consideration relates to whether the
Partnership Interests are validly issued and paid. In the event that the
Partnership issues additional Partnership Interests pursuant to this Section
4.3.B, the General Partner shall make such revisions to this Agreement
(including but not limited to the revisions described in Section 5.4, Section
6.2.C, and Section 8.6) as it determines are necessary to reflect the issuance
of such additional Partnership Interests. Without limiting the foregoing, the
General Partner is expressly authorized to cause the Partnership to issue
Partnership Units for no tangible value or for less than fair market value, so
long as the General Partner concludes in good faith that such issuance of
Partnership Interests is in the best interests of the Partnership.

      C. Issuance of REIT Shares or Other Securities by the General Partner. The
General Partner shall not issue any additional REIT Shares, other shares of
capital stock of the General Partner or New Securities (other than REIT Shares
issued pursuant to Section 8.6 or such shares, stock or securities pursuant to a
dividend or distribution (including any stock split) of REIT Shares to all of
its stockholders or all of its stockholders who hold a particular class of stock
of the General Partner) unless (i) the General Partner shall cause the
Partnership to issue to the General Partner, Partnership Interests or rights,
options, warrants or convertible or exchangeable securities of the Partnership
having designations, preferences and other rights, all such that the economic
interests thereof are substantially similar to those of the REIT Shares, other
shares of capital stock of the General Partner or New Securities issued by the
General Partner and (ii) the General Partner shall make a Capital Contribution
of the net proceeds from the issuance of such additional REIT Shares, other

                                       21
<PAGE>

shares of capital stock or New Securities, as the case may be, and from the
exercise of the rights contained in such additional New Securities, as the case
may be. Without limiting the foregoing, the General Partner is expressly
authorized to issue REIT Shares, other shares of capital stock of the General
Partner or New Securities for no tangible value or for less than fair market
value, and the General Partner is expressly authorized to cause the Partnership
to issue to the General Partner corresponding Partnership Interests, so long as
(x) the General Partner concludes in good faith that such issuance of
Partnership Interests is in the interests of the Partnership; and (y) the
General Partner contributes all proceeds, if any, from such issuance and
exercise to the Partnership.

            In connection with the General Partner's initial public offering of
REIT Shares, any other issuance of REIT Shares, other capital stock of the
General Partner or New Securities, the General Partner shall contribute to the
Partnership, any net proceeds raised in connection with such issuance; provided,
that the General Partner may use a portion of the net proceeds from any offering
to acquire Partnership Units or other assets (provided such other assets are
contributed to the Partnership pursuant to the terms of this Agreement); and
provided further that if the net proceeds actually received by the General
Partner are less than the gross proceeds of such issuance as a result of any
underwriter's discount or other expenses paid or incurred in connection with
such issuance then, except to the extent such net proceeds are used to acquire
Partnership Units, the General Partner shall be deemed to have made a Capital
Contribution to the Partnership in the amount equal to the sum of the net
proceeds of such issuance plus the amount of such underwriter's discount and
other expenses paid by the General Partner (which discount and expense shall be
treated as an expense for the benefit of the Partnership for purposes of Section
7.4). In the case of issuances of REIT Shares, other capital stock of the
General Partner or New Securities pursuant to any Stock Plan at a discount from
fair market value or for no value, the amount of such discount representing
compensation to the employee, as determined by the General Partner, shall be
treated as an expense for the benefit of the Partnership for purposes of Section
7.4 and, as a result, the General Partner shall be deemed to have made a Capital
Contribution to the Partnership in an amount equal to the sum of any net
proceeds of such issuance plus the amount of such expense.

      D. Percentage Interest Adjustments in the Case of Capital Contributions
for Partnership Units. Upon the acceptance of additional Capital Contributions
in exchange for any class or series of Partnership Units, the Percentage
Interest in such class or series of Partnership Units shall be equal to a
fraction, the numerator of which is equal to the amount of cash and the Agreed
Value of the Property contributed as of the time such additional Capital
Contributions are made (an "Adjustment Date") and the denominator of which is
equal to the sum of (i) the Deemed Value of the Partnership Interests of such
class or series (computed as of the Business Day immediately preceding the
Adjustment Date) and (ii) the aggregate Agreed Value of additional Capital
Contributions contributed by all Partners and/or third parties to the
Partnership on such Adjustment Date in such class or series of Partnership
Interests. The Percentage Interest of each other Partner holding Partnership
Interests of such class or series not making a full pro rata Capital
Contribution shall be adjusted to equal a fraction, the numerator of which is
equal to the sum of (i) the Deemed Partnership Interest Value of such Limited
Partner in respect of such class or series (computed as of the Business Day
immediately preceding the Adjustment Date) and (ii) the Agreed Value of
additional Capital Contributions, if any, made by such Partner to the
Partnership in such class or series of Partnership Interests as of such
Adjustment Date, and the denominator of which is equal to the sum of (i) the
Deemed Value of the Partnership Interests of such class or series (computed as
of the Business Day immediately preceding the Adjustment Date), plus (ii) the
aggregate Agreed Value of additional Capital Contributions contributed by all
Partners and/or third parties to the

                                       22
<PAGE>

Partnership on such Adjustment Date in such class or series. Provided, however,
solely for purposes of calculating a Partner's Percentage Interest pursuant to
this Section 4.3.D, (i) in the case of cash Capital Contributions by the General
Partner funded by an offering of REIT Shares or other shares of capital stock of
the General Partner and (ii) in the case of the contribution of properties by
the General Partner which were acquired by the General Partner in exchange for
REIT Shares or other shares of capital stock of the General Partner immediately
prior to such contribution, the General Partner shall be issued a number of
Partnership Units equal and corresponding to the number of such shares issued by
the General Partner in exchange for such cash or Properties, the Partnership
Units held by the other Partners shall not be adjusted, and the Partners'
Percentage Interests shall be adjusted accordingly. The General Partner shall
promptly give each Partner written notice of its Percentage Interest, as
adjusted.

Section 4.4 Other Contribution Provisions

            In the event that any Partner is admitted to the Partnership and is
given (or is treated as having received) a Capital Account at the time of
admission in exchange for services rendered to the Partnership, such transaction
shall be treated by the Partnership and the affected Partner as if the
Partnership had compensated such Partner in cash, and the Partner had
contributed such cash to the capital of the Partnership. In addition, with the
consent of the General Partner, in its sole discretion, one or more Limited
Partners may enter into agreements with the Partnership, in the form of a
guarantee or contribution agreement, which have the effect of providing a
guarantee of certain obligations of the Partnership.

Section 4.5 No Preemptive Rights

            Except to the extent expressly granted by the Partnership pursuant
to another agreement, no Person shall have any preemptive, preferential or other
similar right with respect to (i) providing funds to the Partnership or (ii)
issuance or sale of any Partnership Units or other Partnership Interests.

                                   ARTICLE 5.
                                  DISTRIBUTIONS

Section 5.1 Requirement and Characterization of Distributions

            The General Partner shall cause the Partnership to distribute
quarterly all, or such portion as the General Partner may in its discretion
determine, Available Cash generated by the Partnership to the Partners who are
Partners on the applicable Partnership Record Date with respect to such
distribution, (1) first, with respect to any class or series of Partnership
Interests that are entitled to any preference in distributions, in accordance
with the rights of such class or series of Partnership Interests (and within
such class or series, pro rata in proportion to the respective Percentage
Interests on the applicable Partnership Record Date), and (2) second, with
respect to any class or series of Partnership Interests that are not entitled to
any preference in distributions, pro rata to each such class or series in
accordance with the terms of such class or series to the Partners who are
Partners of such class or series on the Partnership Record Date with respect to
such distribution (and within each such class or series, pro rata in proportion
to the respective Percentage Interests on such Partnership Record Date). Unless
otherwise

                                       23
<PAGE>

expressly provided for herein or in an agreement, if any, entered into in
connection with the creation of a new class or series of Partnership Interests
created in accordance with Article 4, no Partnership Interest shall be entitled
to a distribution in preference to any other Partnership Interest. The General
Partner shall take such reasonable efforts, as determined by it in its sole and
absolute discretion and consistent with its qualification as a REIT, to cause
the Partnership to distribute sufficient amounts to enable the General Partner,
for so long as the General Partner has determined to qualify as a REIT, to pay
stockholder dividends that will (a) satisfy the requirements for qualifying as a
REIT under the Code and Regulations ("REIT Requirements"), and (b) except to the
extent otherwise determined by the General Partner, avoid the imposition of any
federal income or excise tax liability on the General Partner.

Section 5.2 Distributions in Kind

            Except as expressly provided herein, no right is given to any
Partner to demand and receive property other than cash. The General Partner may
determine, in its sole and absolute discretion, to make a distribution in-kind
to the Partners of Partnership assets, and such assets shall be distributed in
such a fashion as to ensure that the fair market value is distributed and
allocated in accordance with Articles 5, 6 and 10.

Section 5.3 Distributions Upon Liquidation

            Notwithstanding Section 5.1, proceeds from a Liquidating Event shall
be distributed to the Partners in accordance with Section 13.2.

Section 5.4 Distributions to Reflect Issuance of Additional Partnership
Interests

            In the event that the Partnership issues additional Partnership
Interests to the General Partner or any Additional Limited Partner pursuant to
Section 4.3.B or 4.3.C, the General Partner shall make such revisions to this
Article 5 as it determines are necessary to reflect the issuance of such
additional Partnership Interests. In the absence of any agreement to the
contrary, an Additional Limited Partner shall be entitled to the distributions
set forth in Section 5.1 (without regard to this Section 5.4) with respect to
the period during which the closing of its contribution to the Partnership
occurs, multiplied by a fraction the numerator of which is the number of days
from and after the date of such closing through the end of the applicable
period, and the denominator of which is the total number of days in such period.

                                   ALLOCATIONS

Section 6.1 Timing and Amount of Allocations of Net Income and Net Loss

            Net Income and Net Loss of the Partnership shall be determined and
allocated with respect to each Partnership Year of the Partnership as of the end
of each such year. Subject to the other provisions of this Article 6, an
allocation to a Partner of a share of Net Income or Net Loss shall be treated as
an allocation of the same share of each item of income, gain, loss or deduction
that is taken into account in computing Net Income or Net Loss.

Section 6.2 General Allocations

        A. Allocation of Net Income and Net Losses.

            (1)    Net Income. Except as otherwise provided in Section 6.3, Net
Income for any Partnership Year shall be allocated to the Partners in the
following manner and order of priority:

                  (a) First, to the General Partner in an amount equal to the
remainder, if any, of the cumulative Net Losses allocated to the General Partner
pursuant to Section 6.2.A.2(c) for all prior Partnership Years minus the
cumulative Net Income allocated to the General Partner pursuant to this Section
6.2.A.(1)(a) for all prior Partnership Years;

                  (b) Second, to each Limited Partner in an amount equal to the
remainder, if any, of the cumulative Net Losses allocated to each such Limited
Partner pursuant to Section 6.2.A.2(b) for all prior Partnership Years minus the
cumulative Net Income allocated to such Limited Partner pursuant to this Section
6.2.A.(1)(b) for all prior Partnership Years;

                  (c) Third, to the General Partner and the Limited Partners in
proportion, and in an amount equal, to the remainder, if any, of the cumulative
Net Losses allocated to each such Partner pursuant to Section 6.2.A.2(a) for all
prior Partnership Years minus the cumulative Net Income allocated to each
Partner pursuant to this Section 6.2.A.(1)(c) for all prior Partnership Years;

                  (d) Fourth, to each of the Partners in accordance with their
respective Percentage Interests.

            To the extent the allocations of Net Income set forth above in any
paragraph of this Section 6.2.A.(1) are not sufficient to entirely satisfy the
allocation set forth in such paragraph, such allocation shall be made in
proportion to the total amount that would have been allocated pursuant to such
paragraph without regard to such shortfall.

            (2) Net Losses. Except as otherwise provided in Section 6.3, Net
Losses for any Partnership Year shall be allocated to the Partners in the
following manner and order of priority:

                  (a) First, to the General Partner and the Limited Partners in
accordance with their respective Percentage Interests (to the extent consistent
with this Section 6.2.A(2)(a)) until the Adjusted Capital Account Balance
(ignoring for this purpose any amounts a Partner is obligated to contribute to
the capital of the Partnership or is deemed obligated to contribute pursuant to
Regulations Section 1.704-1(b)(2)(ii)(c)(2)) of each such Partner is zero;

                  (b) Second, to the Limited Partners to the extent of, and in
proportion to, their Adjusted Capital Account Balance; and

                  (c) Third, to the General Partner.

                                       25
<PAGE>

      B. Allocations to Reflect Issuance of Additional Partnership Interests. In
the event that the Partnership issues additional Partnership Interests to the
General Partner, a Limited Partner or any Additional Limited Partner pursuant to
Section 4.3, the General Partner shall make such revisions to this Section 6.2
as it determines are necessary to reflect the terms of the issuance of such
additional Partnership Interests, including making preferential allocations to
certain classes of Partnership Interests in accordance with any method selected
by the General Partner.

Section 6.3 Additional Allocation Provisions

            Notwithstanding the foregoing provisions of this Article 6:

        A. Regulatory Allocations.

                        (i) Minimum Gain Chargeback. Except as otherwise
provided in Regulations Section 1.704-2(f), notwithstanding the provisions of
Section 6.2, or any other provision of this Article 6, if there is a net
decrease in Partnership Minimum Gain during any Partnership Year, each Holder
shall be specially allocated items of Partnership income and gain for such year
(and, if necessary, subsequent years) in an amount equal to such Holder's share
of the net decrease in Partnership Minimum Gain, as determined under Regulations
Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made
in proportion to the respective amounts required to be allocated to each Holder
pursuant thereto. The items to be allocated shall be determined in accordance
with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 6.3.A(i)
is intended to qualify as a "minimum gain chargeback" within the meaning of
Regulation Section 1.704-2(f) which shall be controlling in the event of a
conflict between such Regulation and this Section 6.3.A(i).

                        (ii) Partner Minimum Gain Chargeback. Except as
otherwise provided in Regulations Section 1.704-2(i)(4), and notwithstanding the
provisions of Section 6.2, or any other provision of this Article 6 (except
Section 6.3.A(i)), if there is a net decrease in Partner Minimum Gain
attributable to a Partner Nonrecourse Debt during any Partnership Year, each
Holder who has a share of the Partner Minimum Gain attributable to such Partner
Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(5), shall be specially allocated items of Partnership income and gain
for such year (and, if necessary, subsequent years) in an amount equal to such
Holder's share of the net decrease in Partner Minimum Gain attributable to such
Partner Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Holder
pursuant thereto. The items to be so allocated shall be determined in accordance
with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section
6.3.A(ii) is intended to qualify as a "chargeback of partner nonrecourse debt
minimum gain" within the meaning of Regulation Section 1.704-2(i) which shall be
controlling in the event of a conflict between such Regulation and this Section
6.3.A(ii).

                        (iii) Nonrecourse Deductions and Partner Nonrecourse
Deductions. Any Nonrecourse Deductions for any Partnership Year shall be
specially allocated to the Holders in accordance with their respective
Percentage Interests. Any Partner

                                       26
<PAGE>

Nonrecourse Deductions for any Partnership Year shall be specially allocated to
the Holder(s) who bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable,
in accordance with Regulations Sections 1.704-2(b)(4) and 1.704-2(i).

                        (iv) Qualified Income Offset. If any Holder unexpectedly
receives an adjustment, allocation or distribution described in Regulations
Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and
gain shall be allocated, in accordance with Regulations Section
1.704-1(b)(2)(ii)(d), to the Holder in an amount and manner sufficient to
eliminate, to the extent required by such Regulations, the Adjusted Capital
Account Deficit of the Holder as quickly as possible provided that an allocation
pursuant to this Section 6.3.A(iv) shall be made if and only to the extent that
such Holder would have an Adjusted Capital Account Deficit after all other
allocations provided in this Article 6 have been tentatively made as if this
Section 6.3.A(iv) were not in this Agreement. It is intended that this Section
6.3.A(iv) qualify and be construed as a "qualified income offset" within the
meaning of Regulations 1.704-1(b)(2)(ii)(d), which shall be controlling in the
event of a conflict between such Regulations and this Section 6.3.A(iv).

                        (v) Gross Income Allocation. In the event any Holder has
a deficit Capital Account at the end of any Partnership Year which is in excess
of the sum of (1) the amount (if any) such Holder is obligated to restore to the
Partnership, and (2) the amount such Holder is deemed to be obligated to restore
pursuant to Regulations Section 1.704-1(b)(2)(ii)(c) or the penultimate
sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such
Holder shall be specially allocated items of Partnership income and gain in the
amount of such excess as quickly as possible, provided, that an allocation
pursuant to this Section 6.3.A(v) shall be made if and only to the extent that
such Holder would have a deficit Capital Account in excess of such sum after all
other allocations provided in this Article 6 have been tentatively made as if
this Section 6.3.A(v) and Section 6.3.A(iv) were not in this Agreement.

                        (vi) Limitation on Allocation of Net Loss. To the extent
any allocation of Net Loss would cause or increase an Adjusted Capital Account
Deficit as to any Holder, such allocation of Net Loss shall be reallocated among
the other Holders in accordance with their respective Percentage Interests,
subject to the limitations of this Section 6.3.A(vi).

                        (vii) Section 754 Adjustment. To the extent an
adjustment to the adjusted tax basis of any Partnership asset pursuant to Code
Section 734(b) or Code Section 743(b) is required, pursuant to Regulations
Section 1.704-1(b)(2)(iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4),
to be taken into account in determining Capital Accounts as the result of a
distribution to a Holder in complete liquidation of his interest in the
Partnership, the amount of such adjustment to the Capital Accounts shall be
treated as an item of gain (if the adjustment increases the basis of the asset)
or loss (if the adjustment decreases such basis) and such gain or loss shall be
specially allocated to the Holders in accordance with their interests in the
Partnership in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2)
applies, or to the Holders to whom such distribution was made in the event that
Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

                        (viii) Curative Allocation. The allocations set forth in
Sections 6.3.A(i), (ii), (iii), (iv), (v), (vi), and (vii) (the "Regulatory
Allocations") are intended to comply with certain regulatory requirements,
including the requirements of Regulations Sections 1.704-1(b) and 1.704-2.
Notwithstanding the provisions of Sections 6.1 and 6.2, the Regulatory
Allocations shall be taken into account in allocating other items of income,
gain, loss and deduction among the Holders so that, to the extent possible, the
net amount of such allocations of other items and the Regulatory Allocations to
each Holder shall be equal to the net amount that would have been allocated to
each such Holder if the Regulatory Allocations had not occurred.

      B. For purposes of determining a Holder's proportional share of the
"excess nonrecourse liabilities" of the Partnership within the meaning of
Regulations Section 1.752-3(a)(3), each Holder's interest in Partnership profits
shall be such Holder's Percentage Interest.

Section 6.4 Tax Allocations

      A. In General. Except as otherwise provided in this Section 6.4, for
income tax purposes each item of income, gain, loss and deduction (collectively,
"Tax Items") shall be allocated among the Holders in the same manner as its
correlative item of "book" income, gain, loss or deduction is allocated pursuant
to Sections 6.2 and 6.3.

      B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding
Section 6.4.A, Tax Items with respect to Partnership property that is
contributed to the Partnership by a Partner shall be shared among the Holders
for income tax purposes pursuant to Regulations promulgated under Section 704(c)
of the Code, so as to take into account the variation, if any, between the basis
of the property to the Partnership and its initial Gross Asset Value. With
respect to Partnership property that is contributed to the Partnership in
connection with the General Partner's initial public offering, such variation
between basis and initial Gross Asset Value shall be taken into account under
the "traditional method" as described in Regulations Section 1.704-3(b). With
respect to other properties contributed to the Partnership, the Partnership
shall account for such variation under any method consistent with Section 704(c)
of the Code and the applicable regulations as chosen by the General Partner. In
the event the Gross Asset Value of any Partnership asset is adjusted pursuant to
subparagraph (b) of the definition of Gross Asset Value (provided in Article 1),
subsequent allocations of Tax Items with respect to such asset shall take
account of the variation, if any, between the adjusted basis of such asset and
its Gross Asset Value in the same manner as under Section 704(c) of the Code and
the applicable regulations consistent with the requirements of Regulations
Section 1.704-1(b)(2)(iv)(g) using any method approved under Section 704(c) of
the Code and the applicable regulations as chosen by the General Partner,
provided, however, that the "traditional method" as described in Regulations
Section 1.704-3(b) shall be used with respect to Partnership Property that is
contributed to the Partnership in connection with the General Partner's initial
public offering.

Code) and to make distributions to its stockholders sufficient to permit the
General Partner to maintain REIT status), the assumption or guarantee of, or
other contracting for, indebtedness and other liabilities, the issuance of

Person in which it has an equity investment from time to time); provided, that,

obligations of any such Persons);

            (13) subject to the other provisions in this Agreement, the
determination of the fair market value of any Partnership property distributed
in kind using such reasonable method of valuation as it may adopt, provided,

of the Partnership or any other Person in which the Partnership has a direct or
indirect interest, or jointly with any such Subsidiary or other Person;

            (19) the exercise of any of the powers of the General Partner

            (23) the amendment and restatement of Exhibit A hereto to reflect

                                       31
<PAGE>

Substituted Limited Partner or otherwise, which amendment and restatement,
notwithstanding anything in this Agreement to the contrary, shall not be deemed
an amendment to this Agreement, as long as the matter or event being reflected
in Exhibit A hereto otherwise is authorized by this Agreement;

            (24) the taking of any and all acts and things necessary or prudent
to ensure that the Partnership will not be classified as a "publicly traded
partnership" taxable as a corporation under Section 7704 of the Code; and

            (25) the delegation to another Person of any powers now or hereafter
granted to the General Partner.

      B. Each of the Limited Partners agrees that the General Partner is
authorized to execute, deliver and perform the above-mentioned agreements and
transactions on behalf of the Partnership without any further act, approval or
vote of the Partners, notwithstanding any other provisions of this Agreement
(except as provided in Section 7.3 or 11.2), the Act or any applicable law, rule
or regulation to the fullest extent permitted under the Act or other applicable
law, rule or regulation. The execution, delivery or performance by the General
Partner or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that
the General Partner may owe the Partnership or the Limited Partners or any other
Persons under this Agreement or of any duty stated or implied by law or equity.

      C. At all times from and after the date hereof, the General Partner may
cause the Partnership to obtain and maintain (i) casualty, liability and other
insurance on the properties of the Partnership and (ii) liability insurance for
the Indemnities hereunder.

      D. At all times from and after the date hereof, the General Partner may
cause the Partnership to establish and maintain working capital and other
reserves in such amounts as the General Partner, in its sole and absolute
discretion, deems appropriate and reasonable from time to time.

      E. Each of the Limited Partners acknowledges that, in exercising its
authority under this Agreement, the General Partner may, but shall be under no
obligation to, take into account the tax consequences to any Partner (including
the General Partner) of any action taken (or not taken) by the General Partner.
The General Partner and the Partnership shall not have liability to a Partner
under this Agreement as a result of any income tax liability incurred by a
Limited Partner as a result of an action (or inaction) by the General Partner
pursuant to its authority under this Agreement.

      F. Except as otherwise provided herein, to the extent the duties of the
General Partner require expenditures of funds to be paid to third parties, the
General Partner shall not have any obligations hereunder except to the extent
that Partnership funds are reasonably available to it for the performance of
such duties, and nothing herein contained shall be deemed to authorize or
require the General Partner, in its capacity as such, to expend its individual
funds for payment to third parties or to undertake any individual liability or
obligation on behalf of the Partnership.

Section 7.2 Certificate of Limited Partnership

            To the extent that such action is determined by the General Partner
to be reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate and do all the things to
maintain the Partnership as a limited partnership (or a partnership in which the
limited partners have limited liability) under the laws of the State of Maryland
and to maintain the Partnership's qualification to do business as a foreign
limited partnership in each other state, the District of Columbia or other
jurisdiction, in which the Partnership may elect to do business or own property.
Subject to the terms of Section 8.5.A(4), the General Partner shall not be
required, before or after filing, to deliver or mail a copy of the Certificate
or any amendment thereto to any Limited Partner. The General Partner shall use
all reasonable efforts to cause to be filed such other certificates or documents
as may be reasonable and necessary or appropriate for the formation,
continuation, qualification and operation of a limited partnership (or a
partnership in which the limited partners have limited liability) in the State
of Maryland, any other state, or the District of Columbia or other jurisdiction,
in which the Partnership may elect to do business or own property.

Section 7.3 Restrictions on General Partner's Authority

      A. The General Partner may not take any action in contravention of an
express prohibition or limitation of this Agreement without the written Consent
of the Limited Partners and may not (i) perform any act that would subject a
Limited Partner to liability as a general partner in any jurisdiction or any
other liability except as provided herein or under the Act; or (ii) enter into
any contract, mortgage, loan or other agreement that prohibits or restricts, or
has the effect of prohibiting or restricting, the ability of a Limited Partner
to exercise its rights to a Redemption in full, except in each case with the
written consent of such Limited Partner.

      B. The General Partner shall not, without the prior Consent of the
Partners (in addition to any Consent of the Limited Partners required by any
other provision hereof), or except as provided in Section 7.3.C, amend, modify
or terminate this Agreement.

      C. Notwithstanding Section 7.3.B, the General Partner shall have the
exclusive power to amend this Agreement as may be required to facilitate or
implement any of the following purposes:

            (1) to add to the obligations of the General Partner or surrender
any right or power granted to the General Partner or any Affiliate of the
General Partner for the benefit of the Limited Partners;

            (2) to reflect the issuance of additional Partnership Interests
pursuant to Sections 4.3.B, 5.4 and 6.2B. or the admission, substitution,
termination, or withdrawal of Partners in accordance with this Agreement (which
may be effected through the replacement of Exhibit A with an amended Exhibit A);

            (3) to set forth or amend the designations, rights, powers, duties
and preferences of the holders of any additional Partnership Interests issued
pursuant to Article 4;

                                       33
<PAGE>

            (4) to reflect a change that is of an inconsequential nature and
does not adversely affect the Limited Partners in any material respect, or to
cure any ambiguity, correct or supplement any provision in this Agreement not
inconsistent with law or with other provisions, or make other changes with
respect to matters arising under this Agreement that will not be inconsistent
with law or with the provisions of this Agreement;

            (5) to satisfy any requirements, conditions, or guidelines contained
in any order, directive, opinion, ruling or regulation of a federal or state
agency or contained in federal or state law;

            (6) to reflect such changes as are reasonably necessary for the
General Partner to maintain its status as a REIT, including changes which may be
necessitated due to a change in applicable law (or an authoritative
interpretation thereof) or a ruling of the IRS;

            (7) to modify, as set forth in the definition of "Capital Account,"
the manner in which Capital Accounts are computed; and

            (8) to amend or modify any provision of this Agreement in connection
with a Termination Transaction.

            The General Partner will provide notice to the Limited Partners when
any action under this Section 7.3.C is taken.

      D. Notwithstanding Sections 7.3.B and 7.3.C, this Agreement shall not be
amended with respect to any Partner adversely affected, and no action may be
taken by the General Partner, without the Consent of such Partner adversely
affected if such amendment or action would (i) convert a Limited Partner's
interest in the Partnership into a general partner's interest (except as the
result of the General Partner acquiring such interest), (ii) modify the limited
liability of a Limited Partner, (iii) alter rights of the Partner to receive
distributions pursuant to Article 5 or Section 13.2.A(4), or the allocations
specified in Article 6 (except as permitted pursuant to Sections 4.3, 5.4, 6.2.B
and Section 7.3.C(3)), (iv) materially alter or modify the rights to a
Redemption or the REIT Shares Amount as set forth in Section 8.6, and related
definitions hereof, or (v) amend this Section 7.3.D. Further, no amendment may
alter the restrictions on the General Partner's authority set forth elsewhere in
this Section 7.3 or in Section 11.2.B without the Consent specified in such
section. This Section 7.3.D does not require unanimous consent of all Partners
adversely affected unless the amendment is to be effective against all partners
adversely affected.

Section 7.4 Reimbursement of the General Partner

      A. Except as provided in this Section 7.4 and elsewhere in this Agreement
(including the provisions of Articles 5 and 6 regarding distributions, payments
and allocations to which it may be entitled), the General Partner shall not be
compensated for its services as general partner of the Partnership.

      B. The Partnership shall be responsible for and shall pay all expenses
relating to the Partnership's and the General Partner's organization, the
ownership of its assets and its operations. The General Partner is hereby
authorized to pay compensation for accounting,

                                       34
<PAGE>

administrative, legal, technical, management and other services rendered to the
Partnership. Except to the extent provided in this Agreement, the General
Partner and its Affiliates shall be reimbursed on a monthly basis, or such other
basis as the General Partner may determine in its sole and absolute discretion,
for all expenses that the General Partner and its Affiliates incur relating to
the ownership and operation of, or for the benefit of, the Partnership
(including, without limitation, administrative expenses); provided, that the
amount of any such reimbursement shall be reduced by any interest earned by the
General Partner with respect to bank accounts or other instruments or accounts
held by it on behalf of the Partnership. The Partners acknowledge that all such
expenses of the General Partner are deemed to be for the benefit of the
Partnership. Such reimbursement shall be in addition to any reimbursement made
as a result of indemnification pursuant to Section 7.7 hereof. In the event that
certain expenses are incurred for the benefit of the Partnership and other
entities (including the General Partner), such expenses will be allocated to the
Partnership and such other entities in such a manner as the General Partner in
its sole and absolute discretion deems fair and reasonable. All payments and
reimbursements hereunder shall be characterized for federal income tax purposes
as expenses of the Partnership incurred on its behalf, and not as expenses of
the General Partner.

      C. If the General Partner shall elect to purchase from its stockholders
REIT Shares for the purpose of delivering such REIT Shares to satisfy an
obligation under any dividend reinvestment program adopted by the General
Partner, any employee stock purchase plan adopted by the General Partner, or any
similar obligation or arrangement undertaken by the General Partner in the
future or for the purpose of retiring such REIT Shares, the purchase price paid
by the General Partner for such REIT Shares and any other expenses incurred by
the General Partner in connection with such purchase shall be considered
expenses of the Partnership and shall be advanced to the General Partner or
reimbursed to the General Partner, subject to the condition that: (i) if such
REIT Shares subsequently are sold by the General Partner, the General Partner
shall pay to the Partnership any proceeds received by the General Partner for
such REIT Shares (which sales proceeds shall include the amount of dividends
reinvested under any dividend reinvestment or similar program; provided, that a
transfer of REIT Shares for Partnership Units pursuant to Section 8.6 would not
be considered a sale for such purposes); and (ii) if such REIT Shares are not
retransferred by the General Partner within thirty (30) days after the purchase
thereof, or the General Partner otherwise determines not to retransfer such REIT
Shares, the General Partner, shall cause the Partnership to redeem a number of
Partnership Units held by the General Partner equal to the number of such REIT
Shares, as adjusted (x) pursuant to Section 7.5 (in the event the General
Partner acquires material assets, other than on behalf of the Partnership) and
(y) for stock dividends and distributions, stock splits and subdivisions,
reverse stock splits and combinations, distributions of rights, warrants or
options, and distributions of evidences of indebtedness or assets relating to
assets not received by the General Partner pursuant to a pro rata distribution
by the Partnership (in which case such advancement or reimbursement of expenses
shall be treated as having been made as a distribution in redemption of such
number of Partnership Units held by the General Partner).

      D. As set forth in Section 4.3, the General Partner shall be treated as
having made a Capital Contribution in the amount of all expenses that it incurs
relating to the General Partner's offering of REIT Shares, other shares of
capital stock of the General Partner or New Securities.

                                       35
<PAGE>

      E. If and to the extent any reimbursements to the General Partner pursuant
to this Section 7.4 constitute gross income of the General Partner (as opposed
to the repayment of advances made by the General Partner on behalf of the
Partnership), such amounts shall constitute guaranteed payments within the
meaning of Section 707(c) of the Code, shall be treated consistently therewith
by the Partnership and all Partners, and shall not be treated as distributions
for purposes of computing the Partners' Capital Accounts.

Section 7.5 Outside Activities of the General Partner

      A. Except in connection with a transaction authorized in Section 11.2,
without the Consent of the Limited Partners, the General Partner shall not,
directly or indirectly, enter into or conduct any business, other than in
connection with the ownership, acquisition and disposition of Partnership
Interests as a General Partner and the management of the business of the
Partnership, its operation as a public reporting company with a class (or
classes) of securities registered under the Exchange Act, its operation as a
REIT and such activities as are incidental to the same. Without the Consent of
the Limited Partners, the General Partner shall not, directly or indirectly,
participate in or otherwise acquire any interest in any real or personal
property, except its General Partner Interest, its minority interest in any
Subsidiary Partnership(s) that the General Partner holds in order to maintain
such Subsidiary Partnership's status as a partnership, and such bank accounts,
similar instruments or other short term investments as it deems necessary to
carry out its responsibilities contemplated under this Agreement and the
Charter. In the event the General Partner desires to contribute cash to any
Subsidiary Partnership to acquire or maintain an interest of 1% or less in the
capital of such partnership, the General Partner may acquire or maintain an
interest of 1% or less in the capital of such partnership, and the General
Partner may acquire such cash from the Partnership as a loan or in exchange for
a reduction in the General Partner's Partnership Units, in an amount equal to
the amount of such cash divided by the Fair Market Value of a REIT Share on the
day such cash is received by the General Partner. Notwithstanding the foregoing,
the General Partner may acquire Properties or other assets in exchange for REIT
Shares or cash, to the extent such Properties or other assets are immediately
contributed by the General Partner to the Partnership, pursuant to the terms
described in Section 4.3.D. Any Limited Partner Interests acquired by the
General Partner, whether pursuant to exercise by a Limited Partner of its right
of Redemption, or otherwise, shall be automatically converted into a General
Partner Interest comprised of an identical number of Partnership Units with the
same rights, priorities and preferences as the class or series so acquired. The
General Partner may also own one hundred percent (100%) of the stock or
interests of one or more Qualified REIT Subsidiaries or limited liability
companies, respectively, provided that any such entity shall be subject to the
limitations of this Section 7.5.A. If, at any time, the General Partner acquires
material assets (other than Partnership Interests or other assets on behalf of
the Partnership) the definition of "REIT Shares Amount" and the definition of
"Deemed Value of Partnership Interests" shall be adjusted, as reasonably
determined by the General Partner, to reflect the relative Fair Market Value of
a share of capital stock of the General Partner relative to the Deemed
Partnership Interest Value of the related Partnership Unit. The General
Partner's General Partner Interest in the Partnership, its minority interest in
any Subsidiary Partnership(s) (held directly or indirectly through a Qualified
REIT Subsidiary) that the General Partner holds in order to maintain such
Subsidiary Partnership's status as a partnership, and interests in such
short-term liquid investments, bank accounts or similar instruments as the
General Partner deems necessary to carry out its responsibilities contemplated
under this Agreement and the Charter are interests which the General Partner is
permitted to acquire and hold for purposes of this Section 7.5.A.

      B. In the event the General Partner exercises its rights under the Charter
to purchase REIT Shares, other capital stock of the General Partner or New
Securities, as the case may be, then the General Partner shall cause the
Partnership to purchase from it a number of Partnership Units equal to the
number of REIT Shares, other capital stock of the General Partner or New
Securities, as the case may be, so purchased on the same terms that the General
Partner purchased such REIT Shares, other capital stock of the General Partner
or New Securities, as the case may be.

Section 7.6 Contracts with Affiliates

      A. The Partnership may lend or contribute to Persons in which it has an
equity investment, and such Persons may borrow funds from the Partnership, on
terms and conditions established in the sole and absolute discretion of the
General Partner. The foregoing authority shall not create any right or benefit
in favor of any Person.

      B. Except as provided in Section 7.5.A, the Partnership may transfer
assets to joint ventures, other partnerships, corporations or other business
entities in which it is or thereby becomes a participant upon such terms and
subject to such conditions consistent with this Agreement and applicable law as
the General Partner in its sole discretion deems advisable.

      C. The General Partner, in its sole and absolute discretion and without
the approval of the Limited Partners, may propose and adopt on behalf of the
Partnership employee benefit plans funded by the Partnership for the benefit of
employees of the General Partner, the Partnership, Subsidiaries of the
Partnership or any Affiliate of any of them in respect of services performed,
directly or indirectly, for the benefit of the Partnership, the General Partner,
or any of the Partnership's Subsidiaries. The General Partner also is expressly
authorized to cause the Partnership to issue to it Partnership Units
corresponding to REIT Shares issued by the General Partner pursuant to any Stock
Plan or any similar or successor plan and to repurchase such Partnership Units
from the General Partner to the extent necessary to permit the General Partner
to repurchase such REIT Shares in accordance with such plan.

      D. Except as expressly permitted by this Agreement, neither the General
Partner nor any of its Affiliates shall sell, transfer or convey any property
to, or purchase any property from, the Partnership, directly or indirectly,
except pursuant to transactions that are determined by the General Partner in
good faith to be fair and reasonable.

      E. The General Partner is expressly authorized to enter into, in the name
and on behalf of the Partnership, a right of first opportunity arrangement and
other conflict avoidance agreements with various Affiliates of the Partnership
and the General Partner, on such terms as the General Partner, in its sole and
absolute discretion, believes are advisable.

Section 7.7 Indemnification

      A. To the fullest extent permitted by law, the Partnership shall indemnify
an Indemnitee from and against any and all losses, claims, damages, liabilities,
joint or several, expenses (including legal fees and expenses), judgments,
fines, settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the Partnership as set forth in this Agreement
in which any Indemnitee may be involved, or is threatened to be involved, as a
party or otherwise, unless it is established that: (i) the act or omission of
the Indemnitee was material to the matter giving rise to the proceeding and
either was committed in bad faith, fraud or was the result of active and
deliberate dishonesty; (ii) the Indemnitee actually received an improper
personal benefit in money, property or services; or (iii) in the case of any
criminal proceeding, the Indemnitee had reasonable cause to believe that the act
or omission was unlawful. Without limitation, the foregoing indemnity shall
extend to any liability of any Indemnitee, pursuant to a

                                       37
<PAGE>

loan guaranty or otherwise, for any indebtedness of the Partnership or any
Subsidiary of the Partnership (including, without limitation, any indebtedness
which the Partnership or any Subsidiary of the Partnership has assumed or taken
subject to), and the General Partner is hereby authorized and empowered, on
behalf of the Partnership, to enter into one or more indemnity agreements
consistent with the provisions of this Section 7.7 in favor of any Indemnitee
having or potentially having liability for any such indebtedness. The
termination of any proceeding by judgment, order, settlement, conviction or upon
a plea of nolo contendere or its equivalent, or any entry of an order of
probation prior to judgment, does not create a presumption that the Indemnitee
did not meet the requisite standard of conduct set forth in this Section 7.7.A.
Any indemnification pursuant to this Section 7.7 shall be made only out of the
assets of the Partnership, and any insurance proceeds from the liability policy
covering the General Partner and any Indemnitee, and neither the General Partner
nor any Limited Partner shall have any obligation to contribute to the capital
of the Partnership or otherwise provide funds to enable the Partnership to fund
its obligations under this Section 7.7, except to the extent otherwise expressly
agreed to by such Partner and the Partnership.

      B. Reasonable expenses incurred by an Indemnitee who is a party to a
proceeding may be paid or reimbursed by the Partnership in advance of the final
disposition of the proceeding upon receipt by the Partnership of (i) a written
affirmation by the Indemnitee of the Indemnitee's good faith belief that the
standard of conduct necessary for indemnification by the Partnership as
authorized in this Section 7.7 has been met, and (ii) a written undertaking by
or on behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.

      C. The indemnification provided by this Section 7.7 shall be in addition
to any other rights to which an Indemnitee or any other Person may be entitled
under any agreement, pursuant to any vote of the Partners, as a matter of law or
otherwise, and shall continue as to an Indemnitee who has ceased to serve in
such capacity unless otherwise provided in a written agreement pursuant to which
such Indemnitee is indemnified.

      D. The Partnership may, but shall not be obligated to, purchase and
maintain insurance, on behalf of the Indemnitees and such other Persons as the
General Partner shall determine, against any liability that may be asserted
against or expenses that may be incurred by such Person in connection with the
Partnership's activities, regardless of whether the Partnership would have the
power to indemnify such Person against such liability under the provisions of
this Agreement.

      E. For purposes of this Section 7.7, the Partnership shall be deemed to
have requested an Indemnitee to serve as fiduciary of an employee benefit plan
whenever the performance by it of its duties to the Partnership also imposes
duties on, or otherwise involves services by, it to the plan or participants or
beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect
to an employee benefit plan pursuant to applicable law shall constitute fines
within the meaning of Section 7.7; and actions taken or omitted by the
Indemnitee with respect to an employee benefit plan in the performance of its
duties for a purpose reasonably believed by it to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is not opposed to the best interests of the Partnership.

                                       38
<PAGE>

      F. In no event may an Indemnitee subject the Limited Partners to personal
liability by reason of the indemnification provisions set forth in this
Agreement.

      G. An Indemnitee shall not be denied indemnification in whole or in part
under this Section 7.7 because the Indemnitee had an interest in the transaction
with respect to which the indemnification applies if the transaction was
otherwise permitted by the terms of this Agreement.

      H. The provisions of this Section 7.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the
Partnership's liability to any Indemnitee under this Section 7.7 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

      I. If and to the extent any reimbursements to the General Partner pursuant
to this Section 7.7 constitute gross income of the General Partner (as opposed
to the repayment of advances made by the General Partner on behalf of the
Partnership) such amounts shall constitute guaranteed payments within the
meaning of Section 707(c) of the Code, shall be treated consistently therewith
by the Partnership and all Partners, and shall not be treated as distributions
for purposes of computing the Partners' Capital Accounts.

      J. Any indemnification hereunder is subject to, and limited by, the
provisions of Section 10-107 of the Act.

      K. In the event the Partnership is made a party to any litigation or
otherwise incurs any loss or expense as a result of or in connection with any
Partner's personal obligations or liabilities unrelated to Partnership business,
such Partner shall indemnify and reimburse the Partnership for all such loss and
expense incurred, including legal fees, and the Partnership interest of such
Partner may be charged therefor. The liability of a Partner under this Section
7.7.K shall not be limited to such Partner's Partnership Interest, but shall be
enforceable against such Partner personally.

Section 7.8 Liability of the General Partner

      A. Notwithstanding anything to the contrary set forth in this Agreement,
none of the General Partner nor any of its officers, directors, agents or
employees shall be liable or accountable in damages or otherwise to the
Partnership, any Partners or any Assignees, or their successors or assigns, for
losses sustained, liabilities incurred or benefits not derived as a result of
errors in judgment or mistakes of fact or law or any act or omission if the
General Partner acted in good faith.

      B. The Limited Partners expressly acknowledge that the General Partner is
acting for the benefit of the Partnership, the Limited Partners and the General
Partner's stockholders collectively. The General Partner is under no obligation
to give priority to the separate interests of the Limited Partners or the
General Partner's stockholders (including, without limitation, the

                                       39
<PAGE>

tax consequences to Limited Partners or Assignees or to stockholders) in
deciding whether to cause the Partnership to take (or decline to take) any
actions. If there is a conflict between the interests of the stockholders of the
General Partner on one hand and the Limited Partners on the other, the General
Partner shall endeavor in good faith to resolve the conflict in a manner not
adverse to either the stockholders of the General Partner or the Limited
Partners; provided, however, that for so long as the General Partner, owns a
controlling interest in the Partnership, any such conflict that cannot be
resolved in a manner not adverse to either the stockholders of the General
Partner or the Limited Partners shall be resolved in favor of the stockholders.
The General Partner shall not be liable under this Agreement to the Partnership
or to any Partner for monetary damages for losses sustained, liabilities
incurred, or benefits not derived by Limited Partners in connection with such
decisions; provided, that the General Partner has acted in good faith.

      C. Subject to its obligations and duties as General Partner set forth in
Section 7.1.A, the General Partner may exercise any of the powers granted to it
by this Agreement and perform any of the duties imposed upon it hereunder either
directly or by or through its agents. The General Partner shall not be
responsible for any misconduct or negligence on the part of any such agent
appointed by it in good faith.

      D. Any amendment, modification or repeal of this Section 7.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the liability of the General Partner and any of its officers,
directors, agents and employee's liability to the Partnership and the Limited
Partners under this Section 7.8 as in effect immediately prior to such
amendment, modification or repeal with respect to claims arising from or
relating to matters occurring, in whole or in part, prior to such amendment,
modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.9 Other Matters Concerning the General Partner

      A. The General Partner may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties.

      B. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and
advisers selected by it, and any act taken or omitted to be taken in reliance
upon the opinion of such Persons as to matters which such General Partner
reasonably believes to be within such Person's professional or expert competence
shall be conclusively presumed to have been done or omitted in good faith and in
accordance with such opinion.

      C. The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and a duly appointed attorney or attorneys-in-fact. Each such attorney
shall, to the extent provided by the General Partner in the power of attorney,
have full power and authority to do and perform all and every act and duty which
is permitted or required to be done by the General Partner hereunder.

                                       40
<PAGE>

      D. Notwithstanding any other provisions of this Agreement or any
non-mandatory provision of the Act, any action of the General Partner on behalf
of the Partnership or any decision of the General Partner to refrain from acting
on behalf of the Partnership, undertaken in the good faith belief that such
action or omission is necessary or advisable in order to protect the ability of
the General Partner, for so long as the General Partner has determined to
qualify as a REIT, to (i) continue to qualify as a REIT or (ii) avoid the
General Partner incurring any taxes under Section 857 or Section 4981 of the
Code, is expressly authorized under this Agreement and is deemed approved by all
of the Limited Partners.

Section 7.10 Title to Partnership Assets

            Title to Partnership assets, whether real, personal or mixed and
whether tangible or intangible, shall be deemed to be owned by the Partnership
as an entity, and no Partners, individually or collectively, shall have any
ownership interest in such Partnership assets or any portion thereof. Title to
any or all of the Partnership assets may be held in the name of the Partnership,
the General Partner or one or more nominees, as the General Partner may
determine, including Affiliates of the General Partner. The General Partner
hereby declares and warrants that any Partnership assets for which legal title
is held in the name of the General Partner or any nominee or Affiliate of the
General Partner shall be held by the General Partner for the use and benefit of
the Partnership in accordance with the provisions of this Agreement; provided,
however, that the General Partner shall use its best efforts to cause beneficial
and record title to such assets to be vested in the Partnership as soon as
reasonably practicable. All Partnership assets shall be recorded as the property
of the Partnership in its books and records, irrespective of the name in which
legal title to such Partnership assets is held.

Section 7.11 Reliance by Third Parties

            Notwithstanding anything to the contrary in this Agreement, any
Person dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority to encumber, sell or otherwise use in any
manner any and all assets of the Partnership and to enter into any contracts on
behalf of the Partnership, and such Person shall be entitled to deal with the
General Partner as if it were the Partnership's sole party in interest, both
legally and beneficially. Each Limited Partner hereby waives any and all
defenses or other remedies which may be available against such Person to
contest, negate or disaffirm any action of the General Partner in connection
with any such dealing. In no event shall any Person dealing with the General
Partner or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or its representatives. Each and
every certificate, document or other instrument executed on behalf of the
Partnership by the General Partner or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and delivery of such certificate, document
or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

            The Limited Partners shall have no liability under this Agreement

of its Affiliates or any officer, director, employee, partner, agent or trustee
of the General Partner, the Partnership or any of their Affiliates, in their
capacity as such) shall take part in the operations, management or control
(within the meaning of the Act) of the Partnership's business, transact any
business in the Partnership's name or have the power to sign documents for or
otherwise bind the Partnership. The transaction of any such business by the
General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner, the Partnership or any of
their Affiliates, in their capacity as such, shall not affect, impair or
eliminate the limitations on the liability of the Limited Partners or Assignees
under this Agreement.

Section 8.3 Outside Activities of Limited Partners

            Subject to any agreements entered into by a Limited Partner or its
Affiliates with the General Partner, Partnership or a Subsidiary, any Limited

stockholder of any Limited Partner shall be entitled to and may have business
interests and engage in business activities in addition to those relating to the
Partnership, including business interests and activities in direct competition
with the Partnership or that are enhanced by the activities of the Partnership.
Neither the Partnership nor any Partners shall have any rights by virtue of this
Agreement in any business ventures of any Limited Partner or Assignee. Subject
to such agreements, none of the Limited Partners nor any other Person shall have
any rights by virtue of this Agreement or the partnership relationship
established hereby in any business ventures of any other Person, other than the
Limited Partners benefiting from the business conducted by the General Partner,
and such Person shall have no obligation pursuant to this Agreement to offer any
interest in any such business ventures to the Partnership, any Limited Partner
or any such other Person, even if such opportunity is of a character which, if
presented to the Partnership, any Limited Partner or such other Person, could be
taken by such Person.

Section 8.4 Return of Capital

            Except pursuant to the rights of Redemption set forth in Section
8.6, no Limited Partner shall be entitled to the withdrawal or return of his or
her Capital Contribution, except to the extent of distributions made pursuant to
this Agreement or upon termination of the Partnership as provided herein. No
Limited Partner or Assignee shall have priority over any other Limited Partner
or Assignee either as to the return of Capital Contributions, or as otherwise
expressly provided in this Agreement, or as to profits, losses, distributions or
credits.

Section 8.5 Rights of Limited Partners Relating to the Partnership

      A. In addition to other rights provided by this Agreement or by the Act,
and except as limited by Section 8.5.C, each Limited Partner shall have the
right, for a purpose reasonably related to such Limited Partner's interest as a
limited partner in the Partnership, upon written demand with a statement of the
purpose of such demand and at such Limited Partner's expense:

            (1) to obtain a copy of the most recent annual and quarterly reports
filed with the Securities and Exchange Commission by the General Partner
pursuant to the Exchange Act, and each communication sent to the stockholders of
the General Partner;

            (2) to obtain a copy of the Partnership's federal, state and local
income tax returns for each Partnership Year;

            (3) to obtain a current list of the name and last known business,
residence or mailing address of each Partner;

            (4) to obtain a copy of this Agreement and the Certificate and all
amendments thereto, together with executed copies of all powers of attorney
pursuant to which this Agreement, the Certificate and all amendments thereto
have been executed; and

            (5) to obtain true and full information regarding the amount of cash
and a description and statement of any other property or services contributed by
each Partner and which each Partner has agreed to contribute in the future, and
the date on which each became a Partner.

      B. The Partnership shall notify each Limited Partner in writing of any
adjustment made in the calculation of the REIT Shares Amount within a reasonable
time after the date such change becomes effective.

      C. Notwithstanding any other provision of this Section 8.5, the General
Partner may keep confidential from the Limited Partners, for such period of time
as the General Partner determines in its sole and absolute discretion to be
reasonable, any information that (i) the General Partner believes to be in the
nature of trade secrets or other information the disclosure of which the General
Partner in good faith believes is not in the best interests of the Partnership
or (ii) the Partnership or the General Partner is required by law or by
agreements with unaffiliated third parties to keep confidential.

Section 8.6 Redemption Rights

      A. On or after the first anniversary of the Effective Date, with respect
to the Partnership Units acquired on or contemporaneously with the Effective
Date, or (ii) the date of issuance of any other Partnership Units, or on or
after such later date as expressly provided in an agreement entered into between
the Partnership and any Limited Partner, each Limited Partner shall have the
right (subject to the terms and conditions set forth herein and in any other
such agreement, as applicable) to require the Partnership to redeem all or a
portion of the Partnership Units held by such Limited Partner (such Partnership
Units being hereafter referred to as "Tendered Units") in exchange for the Cash
Amount (a "Redemption"); provided that the terms of such Partnership Units do
not provide that such

                                       43
<PAGE>

Partnership Units are not entitled to a right of Redemption. Unless otherwise
expressly provided in this Agreement or in a separate agreement entered into
between the Partnership and the holders of such Partnership Units, all
Partnership Units shall be entitled to a right of Redemption hereunder. The
Tendering Partner shall have no right, with respect to any Partnership Units so
redeemed, to receive any distributions paid on or after the Specified Redemption
Date. Any Redemption shall be exercised pursuant to a Notice of Redemption
delivered to the General Partner by the Limited Partner who is exercising the
right (the "Tendering Partner"). The Cash Amount shall be payable to the
Tendering Partner within ten (10) days of the Specified Redemption Date in
accordance with the instructions set forth in the Notice of Redemption.

      B. Notwithstanding Section 8.6.A above, if a Limited Partner has delivered
to the General Partner a Notice of Redemption then the General Partner may, in
its sole and absolute discretion (subject to the limitations on ownership and
transfer of REIT Shares set forth in the Charter), elect to acquire some or all
of the Tendered Units from the Tendering Partner in exchange for the REIT Shares
Amount (as of the Specified Redemption Date) and, if the General Partner so
elects, the Tendering Partner shall sell the Tendered Units to the General
Partner in exchange for the REIT Shares Amount. In such event, the Tendering
Partner shall have no right to cause the Partnership to redeem such Tendered
Units. The General Partner shall promptly give such Tendering Partner written
notice of its election, and the Tendering Partner may elect to withdraw its
redemption request at any time prior to the acceptance of the cash or REIT
Shares Amount by such Tendering Partner.

      C. The REIT Shares Amount, if applicable, shall be delivered as duly
authorized, validly issued, fully paid and nonassessable REIT Shares and, if
applicable, free of any pledge, lien, encumbrance or restriction, other than
those provided in the Charter, the Bylaws of the General Partner, the Securities
Act, relevant state securities or blue sky laws and any applicable registration
rights agreement with respect to such REIT Shares entered into by the Tendering
Partner. Notwithstanding any delay in such delivery (but subject to Section
8.6.E), the Tendering Partner shall be deemed the owner of such REIT Shares for
all purposes, including without limitation, rights to vote or consent, and
receive dividends, as of the Specified Redemption Date. In addition, the REIT
Shares for which the Partnership Units might be exchanged shall also bear a
legend which generally provides the following:

            THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO RESTRICTIONS ON BENEFICIAL AND CONSTRUCTIVE OWNERSHIP AND TRANSFER
FOR THE PURPOSE OF THE CORPORATION'S MAINTENANCE OF ITS STATUS AS A REAL ESTATE
INVESTMENT TRUST ("REIT") UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED
(THE "CODE"). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY
PROVIDED IN THE CORPORATION'S ARTICLES OF AMENDMENT AND RESTATEMENT, (i) NO
PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE CORPORATION'S COMMON
STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF SHARES, WHICHEVER IS MORE
RESTRICTIVE) OF THE OUTSTANDING COMMON STOCK OF THE CORPORATION; (ii) NO PERSON
MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF COMMON STOCK THAT WOULD RESULT
IN THE CORPORATION BEING "CLOSELY HELD" UNDER SECTION 856(h) OF THE CODE OR
OTHERWISE CAUSE THE CORPORATION TO FAIL TO

                                       44
<PAGE>

QUALIFY AS A REIT; AND (iii) NO PERSON MAY TRANSFER SHARES OF COMMON STOCK IF
SUCH TRANSFER WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION BEING OWNED
BY FEWER THAN 100 PERSONS. ANY PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS,
OR ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN, SHARES OF COMMON STOCK IN
VIOLATION OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE CORPORATION. IF
ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP ARE VIOLATED, THE SHARES OF
COMMON STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO THE TRUSTEE
OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE BENEFICIARIES. IN ADDITION,
THE CORPORATION MAY REDEEM SHARES UPON THE TERMS AND CONDITIONS SPECIFIED BY THE
BOARD OF DIRECTORS IN ITS SOLE DISCRETION IF THE BOARD OF DIRECTORS DETERMINES
THAT OWNERSHIP OR A TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS
DESCRIBED ABOVE. FURTHERMORE, UPON THE OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED
TRANSFERS IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB
INITIO. ALL TERMS IN THIS LEGEND THAT ARE DEFINED IN THE ARTICLES OF AMENDMENT
AND RESTATEMENT OF THE CORPORATION SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN
THE ARTICLES OF AMENDMENT AND RESTATEMENT OF THE CORPORATION, AS THE SAME MAY BE
AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON
TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SHARES OF COMMON
STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO
THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE.

      D. Each Limited Partner covenants and agrees with the General Partner that
all Tendered Units shall be delivered to the General Partner free and clear of
all liens, claims and encumbrances whatsoever and should any such liens, claims
and/or encumbrances exist or arise with respect to such Tendered Units, the
General Partner shall be under no obligation to acquire the same. Each Limited
Partner further agrees that, in the event any state or local property transfer
tax is payable as a result of the transfer of its Tendered Units to the General
Partner (or its designee), such Limited Partner shall assume and pay such
transfer tax.

      E. Notwithstanding the provisions of Section 8.6.A, 8.6.B, 8.6.C or any
other provision of this Agreement, a Limited Partner (i) shall not be entitled
to effect a Redemption for cash or an exchange for REIT Shares to the extent the
ownership or right to acquire REIT Shares pursuant to such exchange by such
Partner on the Specified Redemption Date could cause such Partner or any other
Person, or, in the opinion of counsel selected by the General Partner, may cause
such Partner or any other Person, to violate the restrictions on ownership and
transfer of REIT Shares set forth in the Charter and (ii) shall have no rights
under this Agreement to acquire REIT Shares which would otherwise be prohibited
under the Charter. To the extent any attempted Redemption or exchange for REIT
Shares would be in violation of this Section 8.6.E, it shall be null and void ab
initio and such Limited Partner shall not acquire any rights or economic
interest in the cash otherwise payable upon such Redemption or the REIT Shares
otherwise issuable upon such exchange.

                                       45
<PAGE>

      F. Notwithstanding anything herein to the contrary (but subject to Section
8.6.E), with respect to any Redemption or exchange for REIT Shares pursuant to
this Section 8.6:

            (1) All Partnership Units acquired by the General Partner pursuant
thereto shall automatically, and without further action required, be converted
into and deemed to be Limited Partner Interests comprised of the same number and
class of Partnership Units.

            (2) Without the consent of the General Partner, each Limited Partner
may not effect a Redemption for less than 1,000 Partnership Units or, if the
Limited Partner holds less than 1,000 Partnership Units, all of the Partnership
Units held by such Limited Partner.

            (3) Without the consent of the General Partner, each Limited Partner
may not effect a Redemption during the period after the Partnership Record Date
with respect to a distribution and before the record date established by the
General Partner for a distribution to its stockholders of some or all of its
portion of such distribution.

            (4) The consummation of any Redemption or exchange for REIT Shares
shall be subject to the expiration or termination of the applicable waiting
period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended.

            (5) Each Tendering Partner shall continue to own all Partnership
Units subject to any Redemption or exchange for REIT Shares, and be treated as a
Limited Partner with respect to such Partnership Units for all purposes of this
Agreement, until such Partnership Units are transferred to the General Partner
and paid for or exchanged on the Specified Redemption Date. Until a Specified
Redemption Date, the Tendering Partner shall have no rights as a stockholder of
the General Partner with respect to such Tendering Partner's Partnership Units.

      G. In the event that the Partnership issues additional Partnership
Interests to any Additional Limited Partner pursuant to Section 4.3.B, the
General Partner shall make such revisions to this Section 8.6 as it determines
are necessary to reflect the issuance of such additional Partnership Interests.

      H. Notwithstanding any other provision of this Agreement, the General
Partner is authorized to take any action that it determines to be necessary or
appropriate to cause the partnership to comply with any withholding requirements
established under the Code or any other federal, state or local law that apply
upon a Redemption or exchange of Tendered Units. If a Tendering Partner believes
that it is exempt from withholding upon a Redemption or exchange of Tendered
Units, such Partner must furnish the General Partner a FIRPTA certificate or
other documentation requested by the General Partner is a form acceptable to the
General Partner. If the Partnership or the General Partner is required to
withhold and pay over to any taxing authority any amount upon a Redemption or
exchange of Tendered Units and the Cash Amount or the REIT Shares Amount, as the
case may be, equals or exceeds the amount of tax required to be withheld, the
amount withheld shall be treated as an amount received by such Partner in
redemption of its Tendered Units. If the Cash Amount or the REIT Shares Amount,
as the case may be, is less than the amount of tax required to be withheld, the
Tendering Partner shall not receive any Cash Amount or REIT Shares Amount, and
the Tendering Partner shall contribute

                                       46
<PAGE>

the excess of the amount of tax required to be withheld over the Cash Amount or
REIT Shares Amount before such excess taxes are required to be paid to the
taxing authority.

office of the Partnership appropriate books and records with respect to the
Partnership's business, including without limitation, all books and records
necessary to provide to the Limited Partners any information, lists and copies
of documents required to be provided pursuant to Section 9.3. Any records
maintained by or on behalf of the Partnership in the regular course of its
business may be kept on, or be in the form of any information storage device,
provided, that the records so maintained are convertible into clearly legible
written form within a reasonable period of time. The books of the Partnership
shall be maintained, for financial and tax reporting purposes, on an accrual
basis in accordance with generally accepted accounting principles.

Section 9.2 Fiscal Year

            The fiscal year of the Partnership shall be the calendar year.

Section 9.3 Reports

      A. As soon as practicable, but in no event later than 105 days after the
close of each Partnership Year, or such earlier date as they are filed with the
Securities and Exchange Commission, the General Partner shall cause to be mailed
to each Limited Partner as of the close of the Partnership Year, an annual
report containing financial statements of the Partnership, or of the General
Partner if such statements are prepared solely on a consolidated basis with the
General Partner, for such Partnership Year, presented in accordance with
generally accepted accounting principles, such statements to be audited by a
nationally recognized firm of independent public accountants selected by the
General Partner.

      B. As soon as practicable, but in no event later than 45 days after the
close of each calendar quarter (except the last calendar quarter of each year),
or such earlier date as they are filed with the Securities and Exchange
Commission, the General Partner shall cause to be mailed to each Limited Partner
as of the last day of the calendar quarter, a report containing unaudited
financial statements of the Partnership, or of the General Partner, if such
statements are prepared solely on a consolidated basis with the applicable law
or regulation, or as the General Partner determines to be appropriate.

Section 9.4 Nondisclosure of Certain Information

            Notwithstanding the provisions of Sections 9.1 and 9.3, the General
Partner may keep confidential from the Limited Partners any information that the
General Partner believes to be in the nature of trade secrets or other
information the disclosure of which the General Partner in good faith believes
is not in the best interest of the Partnership or which the Partnership is
required by law or by agreements with unaffiliated third parties to keep
confidential.

                                  TAX MATTERS

Section 10.1 Preparation of Tax Returns

            The General Partner shall arrange for the preparation and timely
filing of all returns of Partnership income, gains, deductions, losses and other
items required of the Partnership for federal and applicable state income tax
purposes and shall use all reasonable efforts to furnish, within 90 days of the
close of each taxable year, the tax information reasonably required by Limited
Partners for federal and applicable state income tax reporting purposes. Each
Limited Partner shall promptly provide the General Partner with any information
reasonably requested by the General Partner relating to any Contributed Property
contributed (directly or indirectly) by such Limited Partner to the Partnership.

Section 10.2 Tax Elections

            Except as otherwise provided herein, the General Partner shall, in
its sole and absolute discretion, determine whether to make any available
election pursuant to the Code, including the election under Section 754 of the
Code. The General Partner shall have the right to seek to revoke any such
election (including without limitation, any election under Section 754 of the
Code) upon the General Partner's determination in its sole and absolute
discretion that such revocation is the best interests of the Partners.

Section 10.3 Tax Matters Partner

      A. The General Partner shall be the "tax matters partner" of the
Partnership for federal income tax purposes. Pursuant to Section 6230(e) of the
Code, upon receipt of notice from the IRS of the beginning of an administrative
proceeding with respect to the Partnership, the tax matters partner shall
furnish the IRS with the name, address and profit interest of each of the
Limited Partners and Assignees; provided, however, that such information is
provided to the Partnership by the Limited Partners and Assignees.

      B. The tax matters partner is authorized, but not required:

            (1) to enter into any settlement with the IRS with respect to any
administrative or judicial proceedings for the adjustment of Partnership items
required to be taken into account by a Partner for income tax purposes (such
administrative proceedings being referred to as a "tax audit" and such judicial
proceedings being referred to as "judicial review"), and in the settlement
agreement the tax matters partner may expressly state that such agreement shall
bind all Partners, except that such settlement agreement shall not bind any
Partner (i) who (within the time prescribed pursuant to the Code and
Regulations) files a statement with the IRS providing that the tax matters
partner shall not have the authority to enter into a settlement agreement on
behalf of such Partner or (ii) who is a "notice partner" (as defined in Section
6231 of the Code) or a member of a "notice group" (as defined in Section
6223(b)(2) of the Code);

            (2) in the event that a notice of a final administrative adjustment
at the Partnership level of any item required to be taken into account by a
Partner for tax purposes (a "final adjustment") is mailed to the tax matters
partner, to seek judicial review of such final

                                       48
<PAGE>

adjustment, including the filing of a petition for readjustment with the Tax
Court or the United States Claims Court, or the filing of a complaint for refund
with the District Court of the United States for the district in which the
Partnership's principal place of business is located;

            (3) to intervene in any action brought by any other Partner for
judicial review of a final adjustment;

            (4) to file a request for an administrative adjustment with the IRS
at any time and, if any part of such request is not allowed by the IRS, to file
an appropriate pleading (petition or complaint) for judicial review with respect
to such request;

            (5) to enter into an agreement with the IRS to extend the period for
assessing any tax which is attributable to any item required to be taken into
account by a Partner for tax purposes, or an item affected by such item; and

            (6) to take any other action on behalf of the Partners of the
Partnership in connection with any tax audit or judicial review proceeding to
the extent permitted by applicable law or regulations.

            The taking of any action and the incurring of any expense by the tax
matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of the General
Partner set forth in Section 7.7 shall be fully applicable to the tax matters
partner in its capacity as such.

      C. The tax matters partner shall receive no compensation for its services.
All third party costs and expenses incurred by the tax matters partner in
performing its duties as such (including legal and accounting fees) shall be
borne by the Partnership. Nothing herein shall be construed to restrict the
Partnership from engaging an accounting firm to assist the tax matters partner
in discharging its duties hereunder, so long as the compensation paid by the
Partnership for such services is reasonable.

Section 10.4 Organizational Expenses

            The Partnership shall elect to deduct expenses, if any, incurred by
it in organizing the Partnership ratably over a 60-month period as provided in
Section 709 of the Code.

Section 10.5 Withholding

            Each Limited Partner hereby authorizes the Partnership to withhold
from or pay on behalf of or with respect to such Limited Partner any amount of
federal, state, local, or foreign taxes that the General Partner determines that
the Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such Limited Partner pursuant to this Agreement,
including, without limitation, any taxes required to be withheld or paid by the
Partnership pursuant to Sections 1441, 1442, 1445 or 1446 of the Code. Any
amount paid on behalf of or with respect to a Limited Partner shall constitute a
receivable of the Partnership from such Limited Partner, which receivable shall
be paid by such Limited Partner within 15 days after notice from the General
Partner that such payment must be made unless (i) the Partnership

                                       49
<PAGE>

withholds such payment from a distribution which would otherwise be made to the
Limited Partner or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. Any amounts payable by a Limited
Partner hereunder shall bear interest at the base rate on corporate loans at
large United States money center commercial banks, as published from time to
time in the Wall Street Journal, plus two percentage points (but not higher than
the maximum lawful rate) from the date such amount is due (i.e., 15 days after
demand) until such amount is paid in full. Each Limited Partner shall take such
actions as the Partnership or the General Partner shall request in order to
perfect or enforce the security interest created hereunder.

                            TRANSFERS AND WITHDRAWALS

Section 11.1 Transfer

      A. The term "transfer," when used in this Article 11 with respect to a
Partnership Interest, shall be deemed to refer to a transaction by which a
Partner purports to assign its Partnership Interest to another Person and
includes a sale, assignment, gift (outright or in trust), pledge, encumbrance,
hypothecation, mortgage, exchange or any other disposition by law or otherwise.
The term "transfer" when used in this Article 11 does not include any Redemption
or exchange for REIT Shares pursuant to Section 8.6, except as otherwise
provided herein. No part of the interest of a Limited Partner shall be subject
to the claims of any creditor, any spouse for alimony or support, or to legal
process, and may not be voluntarily or involuntarily alienated or encumbered
except as may be specifically provided for in this Agreement or consented to by
the General Partner.

      B. No Partnership Interest shall be transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article 11.
Any transfer or purported transfer of a Partnership Interest not made in
accordance with this Article 11 shall be null and void ab initio unless
otherwise consented to by the General Partner in its sole and absolute
discretion.

Section 11.2 Transfer of General Partner's Partnership Interest

      A. Except in connection with a Termination Transaction permitted under
Section 11.2.B, the General Partner shall not withdraw from the Partnership and
shall not transfer all or any portion of its interest in the Partnership
(whether by sale, statutory merger or consolidation, liquidation or otherwise),
other than to an Affiliate, without the Consent of the Limited Partners, which
may be given or withheld by each Limited Partner in his, her or its sole and
absolute discretion, and only upon the admission of a successor General Partner
pursuant to Section 12.1. Upon any transfer of a Partnership Interest in
accordance with the provisions of this Section 11.2, the transferee shall become
a Substitute General Partner for all purposes herein, and shall

                                       50
<PAGE>

be vested with the powers and rights of the transferor General Partner, and
shall be liable for all obligations and responsible for all duties of the
General Partner, once such transferee has executed such instruments as may be
necessary to effectuate such admission and to confirm the agreement of such
transferee to be bound by all the terms and provisions of this Agreement with
respect to the Partnership Interest so acquired. It is a condition to any
transfer otherwise permitted hereunder that the transferee assumes, by operation
of law or express agreement, all of the obligations of the transferor General
Partner under this Agreement with respect to such transferred Partnership
Interest, and no such transfer (other than pursuant to a statutory merger or
consolidation wherein all obligations and liabilities of the transferor General
Partner are assumed by a successor corporation by operation of law) shall
relieve the transferor General Partner of its obligations under this Agreement
without the Consent of the Limited Partners, in their reasonable discretion. In
the event the General Partner withdraws from the Partnership in violation of
this Agreement or otherwise, or otherwise dissolves or terminates, or upon the
Incapacity of the General Partner, all of the remaining Partners may elect to
continue the Partnership business by selecting a Substitute General Partner in
accordance with the Act.

      B. The General Partner shall not engage in any merger, consolidation or
other combination with or into another person, sale of all or substantially all
of its assets or any reclassification, recapitalization or change of its
outstanding equity interests ("Termination Transaction") unless either clause
(a) or (b) below is satisfied:

                  (a) in connection with such Termination Transaction all
Limited Partners either will receive, or will have the right to elect to
receive, for each Partnership Unit an amount of cash, securities, or other
property equal to the product of the REIT Shares Amount and the greatest amount
of cash, securities or other property paid to a holder of one REIT Share in
consideration of one REIT Share at any time during the period commencing upon
and continuing after the date on which the Termination Transaction is
consummated; provided, that, if, in connection with the Termination Transaction,
a purchase, tender or exchange offer shall have been made to and accepted by the
holders of more than fifty percent (50%) of the outstanding REIT Shares, each
holder of Partnership Units shall receive, or shall have the right to elect to
receive, the greatest amount of cash, securities, or other property which such
holder would have received had it exercised its right to Redemption (as set
forth in Section 8.6) and received REIT Shares in exchange for its Partnership
Units immediately prior to the expiration of such purchase, tender or exchange
offer and had thereupon accepted such purchase, tender or exchange offer and
then such Termination Transaction shall have been consummated; or

                  (b) the following conditions are met: (i) substantially all of
the assets directly or indirectly owned by the surviving entity are held
directly or indirectly by the Partnership or another limited partnership or
limited liability company which is the survivor of a merger, consolidation or
combination of assets with the Partnership (in each case, the "Surviving
Partnership"); (ii) the holders of Partnership Units own a percentage interest
of the Surviving Partnership based on the relative fair market value of the net
assets of the Partnership and the other net assets of the Surviving Partnership
immediately prior to the consummation of such transaction; (iii) the rights,
preferences and privileges of such holders in the Surviving Partnership are at
least as favorable as those in effect immediately prior to the consummation of
such transaction and as those applicable to any other limited partners or
non-managing members of the Surviving Partnership; and (iv) such rights of the
Limited Partners include at least one of

                                       51
<PAGE>

the following: (a) the right to redeem their interests in the Surviving
Partnership for the consideration available to such persons pursuant to Section
11.2.B(2)(a); or (b) the right to redeem their Partnership Units for cash on
terms equivalent to those in effect with respect to their Partnership Units
immediately prior to the consummation of such transaction, or, if the ultimate
controlling person of the Surviving Partnership has publicly traded common
equity securities, such common equity securities, with an exchange ratio based
on the determination of relative fair market value of such securities and the
REIT Shares.

Section 11.3 Limited Partners' Rights to Transfer

      A. Prior to the first anniversary of the Effective Date, no Limited
Partner shall transfer all or any portion of its Partnership Interest to any
transferee without the consent of the General Partner, which consent may be
withheld in its sole and absolute discretion; provided, however, that any
Limited Partner may, at any time (whether prior to or after such one-year
period), without the consent of the General Partner, (i) transfer all or any
portion of its Partnership Interest to the General Partner, (ii) transfer all or
any portion of its Partnership Interest to an Affiliate, another original
Limited Partner or to an Immediate Family Member, subject to the provisions of
Section 11.6, (iii) transfer all or any portion of its Partnership Interest to a
trust for the benefit of a charitable beneficiary or to a charitable foundation,
subject to the provisions of Section 11.6, and (iv) subject to the provisions of
Section 11.6, pledge (a "Pledge") all or any portion of its Partnership Interest
to a lending institution, which is not an Affiliate of such Limited Partner, as
collateral or security for a bona fide loan or other extension of credit, and
transfer such pledged Partnership Interest to such lending institution in
connection with the exercise of remedies under such loan or extension or credit,
and the transfer of such pledged Partnership Interest by the lender to any
transferee. After such anniversary, each Limited Partner or Assignee (resulting
from a transfer made pursuant to clauses (i)-(iv) of the proviso of the
preceding sentence) shall have the right to transfer all or any portion of its
Partnership Interest, subject to the provisions of Section 11.6 and the
satisfaction of each of the following conditions (in addition to the right of
each such Limited Partner or Assignee to continue to make any such transfer
permitted by clauses (i)-(iv) of such proviso without satisfying either of the
following conditions):

            (1) General Partner Right of First Refusal. The transferring Partner
shall give written notice of the proposed transfer to the General Partner, which
notice shall state (i) the identity of the proposed transferee, and (ii) the
amount and type of consideration proposed to be received for the transferred
Partnership Units. The General Partner shall have ten (10) days upon which to
give the transferring Partner notice of its election to acquire the Partnership
Units on the proposed terms. If it so elects, it shall purchase the Partnership
Units on such terms within ten (10) days after giving notice of such election.
If it does not so elect, the transferring Partner may transfer such Partnership
Units to a third party, on economic terms no more favorable to the transferee
than the proposed terms, subject to the other conditions of this Section 11.3.

            (2) Qualified Transferee. Any transfer of a Partnership Interest
shall be made only to Qualified Transferees.

            It is a condition to any transfer otherwise permitted hereunder that
the transferee assumes by operation of law or express agreement all of the
obligations of the transferor Limited

                                       52
<PAGE>

Partner under this Agreement with respect to such transferred Partnership
Interest and no such transfer (other than pursuant to a statutory merger or
consolidation wherein all obligations and liabilities of the transferor Partner
are assumed by a successor corporation by operation of law) shall relieve the
transferor Partner of its obligations under this Agreement without the approval
of the General Partner, in its reasonable discretion. Notwithstanding the
foregoing, any transferee of any transferred Partnership Interest shall be
subject to any and all ownership limitations contained in the Charter, which may
limit or restrict such transferee's ability to exercise its Redemption rights,
and to the representations in Section 3.4.D. Any transferee, whether or not
admitted as a Substituted Limited Partner, shall take subject to the obligations
of the transferor hereunder. Unless admitted as a Substituted Limited Partner,
no transferee, whether by a voluntary transfer, by operation of law or
otherwise, shall have any rights hereunder, other than the rights of an Assignee
as provided in Section 11.5.

      B. If a Limited Partner is subject to Incapacity, the executor,
administrator, trustee, committee, guardian, conservator, or receiver of such
Limited Partner's estate shall have all the rights of a Limited Partner, but not
more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate, and such power as the Incapacitated Limited
Partner possessed to transfer all or any part of his or its interest in the
Partnership. The Incapacity of a Limited Partner, in and of itself, shall not
dissolve or terminate the Partnership.

      C. The General Partner may prohibit any transfer otherwise permitted under
Section 11.3 by a Limited Partner of his or her Partnership Units if, in the
opinion of legal counsel to the Partnership, such transfer would require the
filing of a registration statement under the Securities Act by the Partnership
or would otherwise violate any federal or state securities laws or regulations
applicable to the Partnership or the Partnership Unit.

Section 11.4 Substituted Limited Partners

      A. No Limited Partner shall have the right to substitute a transferee as a
Limited Partner in his or her place (including any transferee permitted by
Section 11.3). The General Partner shall, however, have the right to consent to
the admission of a transferee of the interest of a Limited Partner pursuant to
this Section 11.4 as a Substituted Limited Partner, which consent may be given
or withheld by the General Partner in its sole and absolute discretion. The
General Partner's failure or refusal to permit a transferee of any such
interests to become a Substituted Limited Partner shall not give rise to any
cause of action, whether at law or in equity, against the Partnership or any
Partner.

      B. A transferee who has been admitted as a Substituted Limited Partner in
accordance with this Article 11 shall have all the rights and powers and be
subject to all the restrictions and liabilities of a Limited Partner under this
Agreement. The admission of any transferee as a Substituted Limited Partner
shall be subject to the transferee executing and delivering to the General
Partner an acceptance of all of the terms and conditions of this Agreement
(including without limitation, the provisions of Section 2.4 and such other
documents or instruments as may be required to effect the admission), each in
form and substance satisfactory to the General Partner) and the acknowledgment
by such transferee that each of the representations and warranties set forth in
Section 3.4 are true and correct with respect to such

                                       53
<PAGE>

transferee as of the date of the transfer of the Partnership Interest to such
transferee and will continue to be true to the extent required by such
representations and warranties.

      C. Upon the admission of a Substituted Limited Partner, the General
Partner shall amend Exhibit A to reflect the name, address, number of
Partnership Units, and Percentage Interest of such Substituted Limited Partner
and to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.

Section 11.5 Assignees

            If the General Partner, in its sole and absolute discretion, does
not consent to the admission of any permitted transferee under Section 11.3 as a
Substituted Limited Partner, as described in Section 11.4, such transferee shall
be considered an Assignee for purposes of this Agreement. An Assignee shall be
entitled to all the rights of an assignee of a limited partnership interest
under the Act, including the right to receive distributions from the Partnership
and the share of Net Income, Net Losses, gain and loss attributable to the
Partnership Units assigned to such transferee, the rights to transfer the
Partnership Units provided in this Article 11, the right of Redemption provided
in Section 8.6, but shall not be deemed to be a holder of Partnership Units for
any other purpose under this Agreement, and shall not be entitled to effect a
Consent with respect to such Partnership Units on any matter presented to the
Limited Partners for approval (such Consent remaining with the transferor
Limited Partner). In the event any such transferee desires to make a further
assignment of any such Partnership Units, such transferee shall be subject to
all the provisions of this Article 11 to the same extent and in the same manner
as any Limited Partner desiring to make an assignment of Partnership Units.
Notwithstanding anything contained in this Agreement to the contrary, as a
condition to becoming an Assignee, any prospective Assignee must first execute
and deliver to the Partnership an acknowledgment that each of the
representations and warranties set forth in Section 3.4 are true and correct
with respect to such prospective Assignee as of the date of the prospective
assignment of the Partnership Interest to such prospective Assignee and will
continue to be true to the extent required by such representations or
warranties.

Section 11.6 General Provisions

      A. No Limited Partner may withdraw from the Partnership other than as a
result of (i) a permitted transfer of all of such Limited Partner's Partnership
Units in accordance with this Article 11 and the transferee(s) of such
Partnership Units being admitted to the Partnership as a Substituted Limited
Partner or (ii) pursuant to the exercise of its right of Redemption of all of
such Limited Partner's Partnership Units under Section 8.6; provided that after
such transfer, exchange or redemption such Limited Partner owns no Partnership
Interest.

      B. Any Limited Partner who shall transfer all of such Limited Partner's
Partnership Units in a transfer permitted pursuant to this Article 11 where such
transferee was admitted as a Substituted Limited Partner or pursuant to the
exercise of its rights of Redemption of all of such Limited Partner's
Partnership Units under Section 8.6 shall cease to be a Limited Partner;
provided that after such transfer, exchange or redemption such Limited Partner
owns no Partnership Interest.

                                       54
<PAGE>

      C. Transfers pursuant to this Article 11 may only be made on the first day
of a fiscal quarter of the Partnership, unless the General Partner otherwise
agrees.

      D. If any Partnership Interest is transferred, assigned or redeemed during
any quarterly segment of the Partnership's Partnership Year in compliance with
the provisions of this Article 11 or transferred or redeemed pursuant to Section
8.6, on any day other than the first day of a Partnership Year, then Net Income,
Net Losses, each item thereof and all other items attributable to such
Partnership Interest for such Partnership Year shall be divided and allocated
between the transferor Partner and the transferee Partner by taking into account
their varying interests during the Partnership Year using a method selected by
the General Partner that is in accordance with Section 706(d) of the Code.
Except as otherwise agreed by the General Partner, all distributions of
Available Cash with respect to which the Partnership Record Date is before the
date of such transfer, assignment, exchange or redemption shall be made to the
transferor Partner, and all distributions of Available Cash thereafter, in the
case of a transfer or assignment other than a redemption, shall be made to the
transferee Partner.

      E. In addition to any other restrictions on transfer herein contained,
including without limitation the provisions of this Article 11 and Section 2.6,
in no event may any transfer or assignment of a Partnership Interest by any
Partner (including pursuant to a Redemption or exchange for REIT Shares by the
Partnership or the General Partner) be made (i) to any person or entity who
lacks the legal right, power or capacity to own a Partnership Interest; (ii) in
violation of applicable law; (iii) except with the consent of the General
Partner, which may be given or withheld in its sole and absolute discretion, of
any component portion of a Partnership Interest, such as the Capital Account, or
rights to distributions, separate and apart from all other components of a
Partnership Interest; (iv) except with the consent of the General Partner, which
may be given or withheld in its sole and absolute discretion, if in the opinion
of legal counsel to the Partnership such transfer could cause a termination of
the Partnership for federal or state income tax purposes (except as a result of
the Redemption or exchange for REIT Shares of all Partnership Interests held by
all Limited Partners or pursuant to a transaction expressly permitted under
Section 11.2); (v) if in the opinion of counsel to the Partnership such transfer
could cause the Partnership to cease to be classified as a partnership for
federal income tax purposes (except as a result of the Redemption or exchange
for REIT Shares of all Partnership Interests held by all Limited Partners); (vi)
if such transfer could, in the opinion of counsel to the Partnership, cause the
Partnership to become, with respect to any employee benefit plan subject to
Title I of ERISA, a "party-in-interest" (as defined in Section 3(14) of ERISA)
or a "disqualified person" (as defined in Section 4975(c) of the Code); (vii) if
such transfer could, in the opinion of counsel to the Partnership, cause any
portion of the assets of the Partnership to constitute assets of any employee
benefit plan pursuant to Department of Labor Regulations Section 2510.2-101;
(viii) if such transfer requires the registration of such Partnership Interest
pursuant to any applicable federal or state securities laws; (ix) except with
the consent of the General Partner, which may be given or withheld in its sole
and absolute discretion, if such transfer (1) could be treated as effectuated
through an "established securities market" or a "secondary market" (or the
substantial equivalent thereof) within the meaning of Section 7704 of the Code,
(2) could cause the Partnership to become a "publicly traded partnership," as
such term is defined in Sections 469(k)(2) or 7704(b) of the Code, (3) could be
in violation of Section 3.4E(5), or (4) could cause the Partnership to fail one
or more of the Safe Harbors (as defined below); (x) if such transfer subjects

Income Security Act of 1974, each as amended; (xi) except with the consent of
the General Partner, which may be given or withheld in its sole discretion, if
the transferee or assignee of such Partnership Interest is unable to make the
representations set forth in Section 3.4.C; (xii) if such transfer is made to a
lender to the Partnership or any Person who is related (within the meaning of
Section 1.752-4(b) of the Regulations) to any lender to the Partnership whose
loan constitutes a Nonrecourse Liability, except with the consent of the General
Partner, which may be given or withheld in its sole and absolute discretion; and
provided, that, as a condition to granting such consent the lender may be
required to enter into an arrangement with the Partnership and the General
Partner to redeem or exchange for the REIT Shares Amount any Partnership Units
in which a security interest is held simultaneously with the time at which such
lender would be deemed to be a partner in the Partnership for purposes of
allocating liabilities to such lender under Section 752 of the Code; or (xiii)
if in the opinion of legal counsel for the Partnership such transfer could
adversely affect the ability of the General Partner to continue to qualify as a
REIT or, except with the consent of the General Partner, which may be given or
withheld in its sole and absolute discretion, subject the General Partner to any
additional taxes under Section 857 or Section 4981 of the Code.

      F. The General Partner shall monitor the transfers of interests in the
Partnership (including any acquisition of Partnership Units by the Partnership
or the General Partner) to determine (i) if such interests could be treated as
being traded on an "established securities market" or a "secondary market (or
the substantial equivalent thereof)" within the meaning of Section 7704 of the
Code and (ii) whether such transfers of interests could result in the
Partnership being unable to qualify for the "safe harbors" set forth in
Regulations Section 1.7704-1 (or such other guidance subsequently published by
the IRS setting forth safe harbors under which interests will not be treated as
"readily tradable on a secondary market (or the substantial equivalent thereof)"
within the meaning of Section 7704 of the Code) (the "Safe Harbors"). The
General Partner shall have the authority (but shall not be required) to take any
steps it determines are necessary or appropriate in its sole and absolute
discretion to prevent any trading of interests which could cause the Partnership
to become a "publicly traded partnership" within the meaning of Code Section
7704, or any recognition by the Partnership of such transfers, or to ensure that
one or more of the Safe Harbors is met.

Section 12.1 Admission of Successor General Partner

            A successor to all of the General Partner's General Partner Interest
pursuant to Section 11.2 who is proposed to be admitted as a successor General
Partner shall be admitted to the Partnership as the General Partner, effective
upon such transfer. Any such transferee shall carry on the business of the
Partnership without dissolution. In each case, the admission shall be subject to
the successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission. In the case
of such admission on any day other than the first day of a Partnership Year, all

Section 12.2 Admission of Additional Limited Partners

      A. After the admission to the Partnership of the initial Limited Partners
on the date hereof, a Person who makes a Capital Contribution to the Partnership
in accordance with this Agreement shall be admitted to the Partnership as an
Additional Limited Partner only upon furnishing to the General Partner (i)
evidence of acceptance in form satisfactory to the General Partner of all of the
terms and conditions of this Agreement, including, without limitation, the power
of attorney granted in Section 2.4 and (ii) such other documents or instruments
as may be required in the discretion of the General Partner in order to effect
such Person's admission as an Additional Limited Partner.

      B. Notwithstanding anything to the contrary in this Section 12.2, no
Person shall be admitted as an Additional Limited Partner without the consent of
the General Partner, which consent may be given or withheld in the General
Partner's sole and absolute discretion. The admission of any Person as an
Additional Limited Partner shall become effective on the date upon which the
name of such Person is recorded on the books and records of the Partnership,
following the receipt of the Capital Contribution in respect of such Limited
Partner and the consent of the General Partner to such admission. If any
Additional Limited Partner is admitted to the Partnership on any day other than
the first day of a Partnership Year, then Net Income, Net Losses, each item
thereof and all other items allocable among Partners and Assignees for such
Partnership Year shall be allocated among such Limited Partner and all other
Partners and Assignees by taking into account their varying interests during the
Partnership Year using a method selected by the General Partner that is in
accordance with Section 706(d) of the Code. All distributions of Available Cash
with respect to which the Partnership Record Date is before the date of such
admission shall be made solely to Partners and Assignees other than the
Additional Limited Partner (other than in its capacity as an Assignee) and,
except as otherwise agreed to by the Additional Limited Partners and the General
Partner, all distributions of Available Cash thereafter shall be made to all
Partners and Assignees including such Additional Limited Partner.

Section 12.3 Amendment of Agreement and Certificate of Limited Partnership

            For the admission to the Partnership of any Partner, the General
Partner shall take all steps necessary and appropriate under the Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 2.4.

                           DISSOLUTION AND LIQUIDATION

Section 13.1 Dissolution

            The Partnership shall not be dissolved by the admission of
Substituted Limited Partners or Additional Limited Partners or by the admission
of a successor General Partner in accordance with the terms of this Agreement.
Upon the withdrawal of the General Partner, any

                                       57
<PAGE>

successor General Partner (selected as described in Section 13.1.B below) shall
continue the business of the Partnership. The Partnership shall dissolve, and
its affairs shall be wound up, upon the first to occur of any of the following
(each a "Liquidating Event"):

      A. the expiration of its term as provided in Section 2.5;

      B. an event of withdrawal of the General Partner, as defined in the Act,
unless, within 90 days after the withdrawal, all of the remaining Partners agree
in writing, in their sole and absolute discretion, to continue the business of
the Partnership and to the appointment, effective as of the date of withdrawal,
of a substitute General Partner;

      C. subject to compliance with Section 11.2 an election to dissolve the
Partnership made by the General Partner, in its sole and absolute discretion;

      D. entry of a decree of judicial dissolution of the Partnership pursuant
to the provisions of the Act;

      E. any sale or other disposition of all or substantially all of the assets
of the Partnership or a related series of transactions that, taken together,
result in the sale or other disposition of all or substantially all of the
assets of the Partnership;

      F. the Incapacity of the General Partner, unless all of the remaining
Partners in their sole and absolute discretion agree in writing to continue the
business of the Partnership and to the appointment, effective as of a date prior
to the date of such Incapacity, of a substitute General Partner;

      G. the Redemption or exchange for REIT Shares of all Partnership Units
(other than those of the General Partner) pursuant to this Agreement; or

      H. a final and non-appealable judgment is entered by a court of competent
jurisdiction ruling that the General Partner is bankrupt or insolvent, or a
final and non-appealable order for relief is entered by a court with appropriate
jurisdiction against the General Partner, in each case under any federal or
state bankruptcy or insolvency laws as now or hereafter in effect, unless prior
to the entry of such order or judgment all of the remaining Partners agree in
writing to continue the business of the Partnership and to the appointment,
effective as of a date prior to the date of such order or judgment, of a
substitute General Partner.

Section 13.2 Winding Up

      A. Upon the occurrence of a Liquidating Event, the Partnership shall
continue solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets, and satisfying the claims of its creditors and Partners.
No Partner shall take any action that is inconsistent with, or not necessary to
or appropriate for, the winding up of the Partnership's business and affairs.
The General Partner (or, in the event there is no remaining General Partner, any
Person elected by a Majority in Interest of the Limited Partners (the
"Liquidator")) shall be responsible for overseeing the winding up and
dissolution of the Partnership and shall take full account of the Partnership's
liabilities and property and the Partnership property shall be liquidated as
promptly as is consistent with obtaining the fair value thereof, and the
proceeds

                                       58
<PAGE>

therefrom (which may, to the extent determined by the General Partner, include
shares of stock in the General Partner) shall be applied and distributed in the
following order:

            (1) First, to the payment and discharge of all of the Partnership's
debts and liabilities to creditors other than the Partners;

            (2) Second, to the payment and discharge of all of the Partnership's
debts and liabilities to the General Partner;

            (3) Third, to the payment and discharge of all of the Partnership's
debts and liabilities to the other Partners; and

            (4) The balance, if any, to the General Partner and Limited Partners
in accordance with their positive Capital Account balances, determined after
taking into account all Capital Account adjustments for all prior periods and
the Partnership taxable year during which the liquidation occurs (other than
those made as a result of the liquidating distribution set forth in this Section
13.2.A(4)).

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13 other than reimbursement of its
expenses as provided in Section 7.4.

      B. Notwithstanding the provisions of Section 13.2.A which require
liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership
the Liquidator determines that an immediate sale of part or all of the
Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2.A, undivided interests in such
Partnership assets as the Liquidator deems not suitable for liquidation. Any
such distributions in-kind shall be made only if, in the good faith judgment of
the Liquidator, such distributions in-kind are in the best interest of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

Section 13.3 Capital Contribution Obligation

            If any Partner has a deficit balance in his or her Capital Account
(after giving effect to all contributions, distributions and allocations for the
taxable years, including the year during which such liquidation occurs), such
Partner shall have no obligation to make any contribution to the capital of the
Partnership with respect to such deficit, and such deficit at any time shall not
be considered a debt owed to the Partnership or to any other Person for any
purpose whatsoever, except to the extent otherwise expressly agreed to by such
Partner and the Partnership.

Section 13.4 Compliance with Timing Requirements of Regulations

            In the discretion of the Liquidator or the General Partner, a pro
rata portion of the distributions that would otherwise be made to the General
Partner and Limited Partners pursuant to this Article 13 may be:

            (1) distributed to a trust established for the benefit of the
General Partner and Limited Partners for the purposes of liquidating Partnership
assets, collecting amounts owed to the Partnership, and paying any contingent or
unforeseen liabilities or obligations of the Partnership or of the General
Partner arising out of or in connection with the Partnership. The assets of any
such trust shall be distributed to the General Partner and Limited Partners from
time to time, in the reasonable discretion of the Liquidator or the General
Partner, in the same proportions and the amount distributed to such trust by the
Partnership would otherwise have been distributed to the General Partner and
Limited Partners pursuant to this Agreement; or

            (2) withheld or escrowed to provide a reasonable reserve for
Partnership liabilities (contingent or otherwise) and to reflect the unrealized
portion of any installment obligations owed to the Partnership, provided, that
such withheld or escrowed amounts shall be distributed to the General Partner
and Limited Partners in the manner and priority set forth in Section 13.2.A as
soon as practicable.

Section 13.5 Deemed Distribution and Recontribution

            Notwithstanding any other provision of this Article 13, in the event
the Partnership is liquidated within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership's
property shall not be liquidated, the Partnership's liabilities shall not be
paid or discharged, and the Partnership's affairs shall not be wound up.
Instead, the Partnership shall be deemed to have contributed all of its assets
and liabilities to a new partnership in exchange a for an interest in the new
partnership. Immediately thereafter, the Partnership shall be deemed to
distribute interests in the new partnership to the General Partner and Limited
Partners in proportion to their respective interests in the Partnership in
liquidation of the Partnership.

Section 13.6 Rights of Limited Partners

            Except as otherwise provided in this Agreement, each Limited Partner
shall look solely to the assets of the Partnership for the return of his Capital
Contribution and shall have no right or power to demand or receive property from
the General Partner. No Limited Partner shall have priority over any other
Limited Partner as to the return of his Capital Contributions, distributions or
allocations.

Section 13.7 Notice of Dissolution

            In the event a Liquidating Event occurs or an event occurs that
would, but for provisions of Section 13.1, result in a dissolution of the
Partnership, the General Partner shall, within 30 days thereafter, provide
written notice thereof to each of the Partners and to all other parties with
whom the Partnership regularly conducts business (as determined in the
discretion of the General Partner) and shall publish notice thereof in a
newspaper of general circulation in

                                       60
<PAGE>

each place in which the Partnership regularly conducts business (as determined
in the discretion of the General Partner).

Section 13.8 Cancellation of Certificate of Limited Partnership

                  Upon the completion of the liquidation of the Partnership cash
and property as provided in Section 13.2, the Partnership shall be terminated
and the Certificate and all qualifications of the Partnership as a foreign
limited partnership in jurisdictions other than the State of Maryland shall be
cancelled and such other actions as may be necessary to terminate the
Partnership shall be taken.

Section 13.9 Reasonable Time for Winding-Up

                  A reasonable time shall be allowed for the orderly winding-up
of the business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2, in order to minimize any losses otherwise attendant
upon such winding-up, and the provisions of this Agreement shall remain in
effect between the Partners during the period of liquidation.

Section 13.10 Waiver of Partition

                  Each Partner hereby waives any right to partition of the
Partnership property.

                                  ARTICLE 14.

Section 14.1 Amendments

         A.       The actions requiring consent or approval of the Partners or
of the Limited Partners pursuant to this Agreement, including Section 7.3, or
otherwise pursuant to applicable law, are subject to the procedures in this
Article 14.

         B.       Amendments to this Agreement requiring the consent or approval
of Limited Partners may be proposed by the General Partner or by Limited
Partners holding twenty-five percent (25%) or more of the Partnership Interests
held by Limited Partners. Following such proposal, the General Partner shall
submit any proposed amendment to the Partners or to the Limited Partners, as
applicable. The General Partner shall seek the written consent of the Limited
Partners on the proposed amendment or shall call a meeting to vote thereon and
to transact any other business that it may deem appropriate. For purposes of
obtaining a written consent, the General Partner may require a response within a
reasonable specified time, but not less than 15 days, and failure to respond in
such time period shall constitute a consent which is consistent with the General
Partner's recommendation (if so recommended) with respect to the proposal;
provided, that, an action shall become effective at such time as requisite
consents are received even if prior to such specified time.

Section 14.2 Action by the Partners

         A.       Meetings of the Partners may be called by the General Partner
and shall be called upon the receipt by the General Partner of a written request

                                       61
<PAGE>

five percent (25%) or more of the Partnership Interests held by Limited
Partners. The notice shall state the nature of the business to be transacted.
Notice of any such meeting shall be given to all Partners not less than seven
days nor more than 30 days prior to the date of such meeting. Partners may vote
in person or by proxy at such meeting. Whenever the vote or Consent of the
Limited Partners or of the Partners is permitted or required under this
Agreement, such vote or Consent may be given at a meeting of Partners or may be
given in accordance with the procedure prescribed in Section 14.1.

         B.       Any action required or permitted to be taken at a meeting of
the Partners may be taken without a meeting if a written consent setting forth
the action so taken is signed by the percentage as is expressly required by this
Agreement for the action in question. Such consent may be in one instrument or
in several instruments, and shall have the same force and effect as a vote of
the Percentage Interests of the Partners (expressly required by this Agreement).
Such consent shall be filed with the General Partner. An action so taken shall
be deemed to have been taken at a meeting held on the effective date so
certified.

         C.       Each Limited Partner may authorize any Person or Persons to
act for him by proxy on all matters in which a Limited Partner is entitled to
participate, including waiving notice of any meeting, or voting or participating
at a meeting. Every proxy must be signed by the Limited Partner or his
attorney-in-fact. No proxy shall be valid after the expiration of 11 months from
the date thereof unless otherwise provided in the proxy. Every proxy shall be
revocable at the pleasure of the Limited Partner executing it.

         D.       Each meeting of Partners shall be conducted by the General
Partner or such other Person as the General Partner may appoint pursuant to such
rules for the conduct of the meeting as the General Partner or such other Person
deems appropriate.

         E.       On matters on which Limited Partners are entitled to vote,
each Limited Partner shall have a vote equal to the number of Partnership Units
held.

                        CONSTRUCTIVE OWNERSHIP DEFINITION

                  The term "Constructively Owns" means ownership determined
through the application of the constructive ownership rules of Section 318 of
the Code, as modified by Section 856(d)(5) of the Code. Generally, these rules
provide the following:

                  a.       an individual is considered as owning the Ownership
Interest (defined below) that is owned, actually or constructively, by or for
his spouse, his children, his grandchildren, and his parents;

                  b.       an Ownership Interest that is owned, actually or
constructively, by or for a partnership, limited liability company or estate is
considered as owned proportionately by its partners or beneficiaries;

                  c.       an Ownership Interest that is owned, actually or
constructively, by or for a trust is considered as owned by its beneficiaries in
proportion to the actuarial interest of such beneficiaries (provided, however,
that in the case of a "grantor trust" the Ownership Interest will be considered
as owned by the grantors);

                  d.       if ten (10) percent or more in value of the stock in
a corporation is owned, actually or constructively, by or for any person, such
person shall be considered as owning the Ownership Interest that is owned,
actually or constructively, by or for such corporation in that proportion which
the value of the stock which such person so owns bears to the value of all the
stock in such corporation;

                  e.       an Ownership Interest that is owned, actually or
constructively, by or for a partner or member which actually or constructively
owns a 25% or greater capital interest or profits interest in a partnership or
limited liability company, or by or to or for a beneficiary of an estate or
trust shall be considered as owned by the partnership, limited liability
company, estate, or trust (or, in the case of a grantor trust, the grantors);

                  f.       if ten (10) percent or more in value of the stock in
a corporation is owned, actually or constructively, by or for any person, such
corporation shall be considered as owning the Ownership Interest that is owned,
actually or constructively, by or for such person;

                  g.       if any person has an option to acquire an Ownership
Interest (including an option to acquire an option or any one of a series of
such options), such Ownership Interest shall be considered as owned by such
person;

                  h.       an Ownership Interest that is constructively owned by
a person by reason of the application of the rules described in paragraphs (a)
through (g) above shall, for purposes of applying paragraphs (a) through (g), be
considered as actually owned by such person provided, however, that (i) an
Ownership Interest constructively owned by an individual by reason of paragraph
(a) shall not be considered as owned by him for purposes of again applying
paragraph (a) in order to make another the constructive owner of such Ownership
Interest, (ii) an Ownership Interest constructively owned by a partnership,
estate, trust, or corporation by reason

                                      C-1
<PAGE>

of the application of paragraphs (e) or (f) shall not be considered as owned by
it for purposes of applying paragraphs (b), (c), or (d) in order to make another
the constructive owner of such Ownership Interest, (iii) if an Ownership
Interest may be considered as owned by an individual under paragraphs (a) or
(g), it shall be considered as owned by him under paragraph (g), and (iv) for
purposes of the above described rules, an S corporation shall be treated as a
partnership and any stockholder of the S corporation shall be treated as a
partner of such partnership except that this rule shall not apply for purposes
of determining whether stock in the S corporation is constructively owned by any
person.

                  i.       For purposes of the above summary of the constructive
ownership rules, the term "Ownership Interest" means the ownership of stock with
respect to a corporation and, with respect to any other type of entity, the
ownership of an interest in either its assets or net profits.
